+%
+% Available class options
+% e.g., \documentclass[10pt,conference]{IEEEtran}
+%
+% *** choose only one from each category ***
+%
+% 9pt, 10pt, 11pt, 12pt
+% Sets normal font size. The default is 10pt.
+%
+% conference, journal, technote, peerreview, peerreviewca
+% determines format mode - conference papers, journal papers,
+% correspondence papers (technotes), or peer review papers. The user
+% should also select 9pt when using technote. peerreview is like
+% journal mode, but provides for a single-column "cover" title page for
+% anonymous peer review. The paper title (without the author names) is
+% repeated at the top of the page after the cover page. For peer review
+% papers, the \IEEEpeerreviewmaketitle command must be executed (will
+% automatically be ignored for non-peerreview modes) at the place the
+% cover page is to end, usually just after the abstract (keywords are
+% not normally used with peer review papers). peerreviewca is like
+% peerreview, but allows the author names to be entered and formatted
+% as with conference mode so that author affiliation and contact
+% information can be easily seen on the cover page.
+% The default is journal.
+%
+% draft, draftcls, draftclsnofoot, final
+% determines if paper is formatted as a widely spaced draft (for
+% handwritten editor comments) or as a properly typeset final version.
+% draftcls restricts draft mode to the class file while all other LaTeX
+% packages (i.e., \usepackage{graphicx}) will behave as final - allows
+% for a draft paper with visible figures, etc. draftclsnofoot is like
+% draftcls, but does not display the date and the word "DRAFT" at the foot
+% of the pages. If using one of the draft modes, the user will probably
+% also want to select onecolumn.
+% The default is final.
+%
+% letterpaper, a4paper, cspaper
+% determines paper size: 8.5in X 11in, 210mm X 297mm or 7.875in X 10.75in.
+% Changing the paper size in the standard journal and conference modes
+% will not alter the typesetting of the document - only the margins will
+% be affected. In particular, documents using the a4paper option will
+% have reduced side margins (A4 is narrower than US letter) and a longer
+% bottom margin (A4 is longer than US letter). For both cases, the top
+% margins will be the same and the text will be horizontally centered.
+% For the compsoc conference and draft modes, it is the margins that will
+% remain constant, and thus the text area size will vary, with changes in
+% the paper size.
+% The cspaper option is the special ``trim'' paper size (7.875in x 10.75in)
+% used in the actual publication of Computer Society journals. Under
+% compsoc journal mode, this option does not alter the typesetting of the
+% document. Authors should invoke the cspaper option only if requested to
+% do so by the editors of the specific journal they are submitting to.
+% For final submission to the IEEE, authors should generally use US letter
+% (8.5 X 11in) paper unless otherwise instructed. Note that authors should
+% ensure that all post-processing (ps, pdf, etc.) uses the same paper
+% specificiation as the .tex document. Problems here are by far the number
+% one reason for incorrect margins. IEEEtran will automatically set the
+% default paper size under pdflatex (without requiring any change to
+% pdftex.cfg), so this issue is more important to dvips users. Fix
+% config.ps, config.pdf, or ~/.dvipsrc for dvips, or use the
+% dvips -t papersize option instead as needed. For the cspaper option,
+% the corresponding dvips paper name is "ieeecs".
+% See the testflow documentation
+% http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow
+% for more details on dvips paper size configuration.
+% The default is letterpaper.
+%
+% oneside, twoside
+% determines if layout follows single sided or two sided (duplex)
+% printing. The only notable change is with the headings at the top of
+% the pages.
+% The default is oneside.
+%
+% onecolumn, twocolumn
+% determines if text is organized into one or two columns per page. One
+% column mode is usually used only with draft papers.
+% The default is twocolumn.
+%
+% comsoc, compsoc, transmag
+% Use the format of the IEEE Communications Society, IEEE Computer Society
+% or IEEE Transactions on Magnetics, respectively.
+%
+% romanappendices
+% Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
+% now defaults to Alpha "Appendix A" convention - the opposite of what
+% v1.6b and earlier did.
+%
+% captionsoff
+% disables the display of the figure/table captions. Some IEEE journals
+% request that captions be removed and figures/tables be put on pages
+% of their own at the end of an initial paper submission. The endfloat
+% package can be used with this class option to achieve this format.
+%
+% nofonttune
+% turns off tuning of the font interword spacing. Maybe useful to those
+% not using the standard Times fonts or for those who have already "tuned"
+% their fonts.
+% The default is to enable IEEEtran to tune font parameters.
+%

+% usage: \@IEEEextracttoken*{}
+% \@IEEEextracttoken fully expands its argument (which it then stores in
+% \@IEEEextracttokenarg) via \edef and then the meaning of the first
+% nonbrace (but including the empty group) token found is assigned via \let
+% to \@IEEEextractedtoken as well as stored in the macro
+% \@IEEEextractedtokenmacro. Tokens that would otherwise be discarded during
+% the acquisition of the first are stored in \@IEEEextractedtokensdiscarded,
+% however their original relative brace nesting depths are not guaranteed to
+% be preserved.
+% If the argument is empty, or if a first nonbrace token does not exist (or
+% is an empty group), \@IEEEextractedtoken will be \relax and
+% \@IEEEextractedtokenmacro and \@IEEEextractedtokensdiscarded will be empty.
+%
+% For example:
+% \@IEEEextracttoken{{{ab}{cd}}{{ef}g}}
+% results in:
+%
+% \@IEEEextracttokenarg ==> a macro containing {{ab}{cd}}{{ef}g}
+% \@IEEEextractedtoken ==> the letter a
+% \@IEEEextractedtokenmacro ==> a macro containing a
+% \@IEEEextractedtokensdiscarded ==> a macro containing bcd{ef}g
+%
+% the *-star form, \@IEEEextracttoken*, does not expand its argument

+% V1.6, we are now going to fine tune the interword spacing
+% The default interword glue for Times under TeX appears to use a
+% nominal interword spacing of 25% (relative to the font size, i.e., 1em)
+% a maximum of 40% and a minimum of 19%.
+% For example, 10pt text uses an interword glue of:
+%
+% 2.5pt plus 1.49998pt minus 0.59998pt
+%
+% However, the IEEE allows for a more generous range which reduces the need
+% for hyphenation, especially for two column text. Furthermore, the IEEE
+% tends to use a little bit more nominal space between the words.
+% The IEEE's interword spacing percentages appear to be:
+% 35% nominal
+% 23% minimum
+% 50% maximum
+% (They may even be using a tad more for the largest fonts such as 24pt.)
+%
+% for bold text, the IEEE increases the spacing a little more:
+% 37.5% nominal
+% 23% minimum
+% 55% maximum
+
+% here are the interword spacing ratios we'll use
+% for medium (normal weight)

+% **** V1.3 ENHANCEMENTS ****
+% Itemize, Enumerate and Description (IED) List Controls
+% ***************************
+%
+%
+% The IEEE seems to use at least two different values by
+% which ITEMIZED list labels are indented to the right
+% For The Journal of Lightwave Technology (JLT) and The Journal
+% on Selected Areas in Communications (JSAC), they tend to use
+% an indention equal to \parindent. For Transactions on Communications
+% they tend to indent ITEMIZED lists a little more--- 1.3\parindent.
+% We'll provide both values here for you so that you can choose
+% which one you like in your document using a command such as:
+% setlength{\IEEEilabelindent}{\IEEEilabelindentB}
+\newdimen\IEEEilabelindentA
+\IEEEilabelindentA \parindent
+
+\newdimen\IEEEilabelindentB
+\IEEEilabelindentB 1.3\parindent
+% However, we'll default to using \parindent
+% which makes more sense to me
+\newdimen\IEEEilabelindent
+\IEEEilabelindent \IEEEilabelindentA
+
+
+% This controls the default amount the enumerated list labels
+% are indented to the right.
+% Normally, this is the same as the paragraph indention
+\newdimen\IEEEelabelindent
+\IEEEelabelindent \parindent
+
+% This controls the default amount the description list labels
+% are indented to the right.
+% Normally, this is the same as the paragraph indention
+\newdimen\IEEEdlabelindent
+\IEEEdlabelindent \parindent
+
+% This is the value actually used within the IED lists.
+% The IED environments automatically set its value to
+% one of the three values above, so global changes do
+% not have any effect
+\newdimen\IEEElabelindent
+\IEEElabelindent \parindent
+
+% The actual amount labels will be indented is
+% \IEEElabelindent multiplied by the factor below
+% corresponding to the level of nesting depth
+% This provides a means by which the user can
+% alter the effective \IEEElabelindent for deeper
+% levels
+% There may not be such a thing as correct "standard IEEE"
+% values. What the IEEE actually does may depend on the specific
+% circumstances.
+% The first list level almost always has full indention.
+% The second levels I've seen have only 75% of the normal indentation
+% Three level or greater nestings are very rare. I am guessing
+% that they don't use any indentation.
+\def\IEEElabelindentfactori{1.0} % almost always one
+\def\IEEElabelindentfactorii{0.75} % 0.0 or 1.0 may be used in some cases
+\def\IEEElabelindentfactoriii{0.0} % 0.75? 0.5? 0.0?
+\def\IEEElabelindentfactoriv{0.0}
+\def\IEEElabelindentfactorv{0.0}
+\def\IEEElabelindentfactorvi{0.0}
+
+% value actually used within IED lists, it is auto
+% set to one of the 6 values above
+% global changes here have no effect
+\def\IEEElabelindentfactor{1.0}
+
+% This controls the default spacing between the end of the IED
+% list labels and the list text, when normal text is used for
+% the labels.
+% compsoc uses a larger value here, but we'll set that later
+% in the class so that this code block area can be extracted
+% as-is for IEEEtrantools.sty
+\newdimen\IEEEiednormlabelsep
+\IEEEiednormlabelsep 0.6em
+
+% This controls the default spacing between the end of the IED
+% list labels and the list text, when math symbols are used for
+% the labels (nomenclature lists). The IEEE usually increases the
+% spacing in these cases
+\newdimen\IEEEiedmathlabelsep
+\IEEEiedmathlabelsep 1.2em
+
+% This controls the extra vertical separation put above and
+% below each IED list. the IEEE usually puts a little extra spacing
+% around each list. However, this spacing is barely noticeable.
+% compsoc uses a larger value here, but we'll set that later
+% in the class so that this code block area can be extracted
+% as-is for IEEEtrantools.sty
+\newskip\IEEEiedtopsep
+\IEEEiedtopsep 2pt plus 1pt minus 1pt
+
+
+% This command is executed within each IED list environment
+% at the beginning of the list. You can use this to set the
+% parameters for some/all your IED list(s) without disturbing
+% global parameters that affect things other than lists.
+% i.e., renewcommand{\IEEEiedlistdecl}{\setlength{\labelsep}{5em}}
+% will alter the \labelsep for the next list(s) until
+% \IEEEiedlistdecl is redefined.
+\def\IEEEiedlistdecl{\relax}
+
+% This command provides an easy way to set \leftmargin based
+% on the \labelwidth, \labelsep and the argument \IEEElabelindent
+% Usage: \IEEEcalcleftmargin{width-to-indent-the-label}
+% output is in the \leftmargin variable, i.e., effectively:
+% \leftmargin = argument + \labelwidth + \labelsep
+% Note controlled spacing here, shield end of lines with %
+\def\IEEEcalcleftmargin#1{\setlength{\leftmargin}{#1}%
+\addtolength{\leftmargin}{\labelwidth}%
+\addtolength{\leftmargin}{\labelsep}}
+
+% This command provides an easy way to set \labelwidth to the
+% width of the given text. It is the same as
+% \settowidth{\labelwidth}{label-text}
+% and useful as a shorter alternative.
+% Typically used to set \labelwidth to be the width
+% of the longest label in the list
+\def\IEEEsetlabelwidth#1{\settowidth{\labelwidth}{#1}}
+
+% When this command is executed, IED lists will use the
+% IEEEiedmathlabelsep label separation rather than the normal
+% spacing. To have an effect, this command must be executed via
+% the \IEEEiedlistdecl or within the option of the IED list
+% environments.
+\def\IEEEusemathlabelsep{\setlength{\labelsep}{\IEEEiedmathlabelsep}}
+
+% A flag which controls whether the IED lists automatically
+% calculate \leftmargin from \IEEElabelindent, \labelwidth and \labelsep
+% Useful if you want to specify your own \leftmargin
+% This flag must be set (\IEEEnocalcleftmargintrue or \IEEEnocalcleftmarginfalse)
+% via the \IEEEiedlistdecl or within the option of the IED list
+% environments to have an effect.
+\newif\ifIEEEnocalcleftmargin
+\IEEEnocalcleftmarginfalse
+
+% A flag which controls whether \IEEElabelindent is multiplied by

+% internal variable to indicate type of IED label

+% 0 - left; 1 - center; 2 - right
+\def\@IEEEiedjustify{0}
+
+
+% commands to allow the user to control IED
+% label justifications. Use these commands within
+% the IED environment option or in the \IEEEiedlistdecl
+% Note that changing the normal list justifications
+% is nonstandard and the IEEE may not like it if you do so!
+% I include these commands as they may be helpful to
+% those who are using these enhanced list controls for
+% other non-IEEE related LaTeX work.
+% itemize and enumerate automatically default to right
+% justification, description defaults to left.

+
+% V1.6, we need to make \footnotesep responsive to changes
+% in \baselineskip or strange spacings will result when in
+% draft mode. Here is a little LaTeX secret - \footnotesep
+% determines the height of an invisible strut that is placed
+% *above* the baseline of footnotes after the first. Since
+% LaTeX considers the space for characters to be 0.7\baselineskip
+% above the baseline and 0.3\baselineskip below it, we need to
+% use 0.7\baselineskip as a \footnotesep to maintain equal spacing
+% between all the lines of the footnotes. The IEEE often uses a tad
+% more, so use 0.8\baselineskip. This slightly larger value also helps
+% the text to clear the footnote marks. Note that \thanks in IEEEtran
+% uses its own value of \footnotesep which is set in \maketitle.

+% The meaning of the first nonbrace (but including the empty group) token
+% within this first group is assigned via \let to \@IEEEextractedfirsttoken
+% as well as stored in the macro \@IEEEextractedfirsttokenmacro. If a first
+% nonbrace token does not exist (or is an empty group), these will be \relax
+% and empty, respectively. Tokens that would otherwise be discarded during
+% the acquisition of the first token in the first group are stored in
+% \@IEEEextractedfirsttokensdiscarded, however their original relative brace
+% nesting depths are not guaranteed to be preserved.
+% The first group within this first group is stored in the macro
+% \@IEEEextractedfirstfirstgroup.
+% Likewise for the next group after the first: \@IEEEextractednextgroup,
+% \@IEEEextractednextfirstgroup, \@IEEEextractednextgroupfirsttoken,
+% \@IEEEextractednextgroupfirsttokenmacro, and
+% \@IEEEextractednextfirsttokensdiscarded.
+% All tokens/groups after the first group, including any enclosing braces,
+% are stored in the macro \@IEEEextractedafterfirstgroupremain which will
+% be empty if none exist.
+%
+% For example:
+% \@IEEEextracttokengroups{{{ab}{cd}}{{ef}g}}
+% will result in:
+%
+% \@IEEEextracttokengroupsarg ==> a macro containing {{ab}{cd}}{{ef}g}
+% \@IEEEextractedfirstgroup ==> a macro containing {ab}{cd}
+% \@IEEEextractedafterfirstgroupremain ==> a macro containing {{ef}g}
+% \@IEEEextractedfirsttoken ==> the letter a
+% \@IEEEextractedfirsttokenmacro ==> a macro containing a
+% \@IEEEextractedfirsttokensdiscarded ==> a macro containing bcd
+% \@IEEEextractedfirstfirstgroup ==> a macro containing ab
+% \@IEEEextractednextgroup ==> a macro containing {ef}g
+% \@IEEEextractednextfirsttoken ==> the letter e
+% \@IEEEextractednextfirsttokenmacro ==> a macro containing e
+% \@IEEEextractednextfirsttokensdiscarded ==> a macro containing fg
+% \@IEEEextractednextfirstgroup ==> a macro containing ef
+%
+% If given an empty argument, \@IEEEextractedfirsttoken and
+% \@IEEEextractednextfirsttoken will be set to \relax
+% and all the macros will be empty.

+% \IEEEauthorrefmark{} produces a footnote type symbol to indicate author affiliation.
+% When given an argument of 1 to 9, \IEEEauthorrefmark{} follows the standard LaTeX footnote
+% symbol sequence convention. However, for arguments 10 and above, \IEEEauthorrefmark{}
+% reverts to using lower case roman numerals, so it cannot overflow. Do note that you
+% cannot use \footnotemark[] in place of \IEEEauthorrefmark{} within \author as the footnote
+% symbols will have been turned off to prevent \thanks from creating footnote marks.
+% \IEEEauthorrefmark{} produces a symbol that appears to LaTeX as having zero vertical

+% \IEEEquantizevspace[output dimen register]{object}[object decl]
+% {top baselineskip}
+% [offset][prevdepth][lineskip limit][lineskip]
+% {unit height}{nominal vspace}{minimum vspace}
+%
+% Calculates and creates the vspace needed to make the combined height with
+% the given object an integer multiple of the given unit height. This command
+% is more general than the older \@IEEEdynamictitlevspace it replaces.
+%
+% The star form has no effect at present, but is reserved for future use.
+%
+% If the optional argument [output dimen register] is given, the calculated
+% vspace height is stored in the given output dimen (or skip) register
+% and no other action is taken, otherwise the object followed by a vspace*
+% of the appropriate height is evaluated/output.
+%
+% The optional object decl (declarations) is code that is evaluated just
+% before the object's height is evaluated. Its intented purpose is to allow
+% for the alteration or disabling of code within the object during internal
+% height evaluation (e.g., \long\def\thanks#1{\relax} ).
+% This special code is not invoked if/when the object is rendered at the end.
+%
+% The nominal vspace is the target value of the added vspace and the minimum
+% vspace is the lower allowed limit. The vspacer will be the value that achieves
+% integral overall height, in terms of the given unit height, that is closest
+% to the nominal vspace and that is not less than the specified minimum vspace.
+%
+% The line spacing algorithm of TeX is somewhat involved and requires special
+% care with regard to the first line of a vertical list (which is indicated
+% when \prevdepth is -1000pt or less). top baselineskip specifies the
+% baselineskip or topskip used prior to the object. If the height of the
+% first line of the object is greater than the given top baselineskip, then
+% the top baselineskip is subtracted from the height of the first line and
+% that difference is considered along with the rest of the object height
+% (because the object will be shifted down by an amount =
+% top line height - top baselineskip). Otherwise, the height of the first line
+% of the object is ignored as far as the calculations are concerned.
+% This algorithm is adequate for objects that appear at the top of a page
+% (e.g., titles) where \topskip spacing is used.
+%
+% However, as explained on page 78 of the TeXbook, interline spacing is more
+% complex when \baselineskip is being used (indicated by \prevdepth >
+% -1000pt). The four optional parameters offset, prevdepth, lineskip limit and
+% lineskip are assumed to be equal to be 0pt, \prevdepth, \lineskiplimit and
+% \lineskip, respectively, if they are omitted.
+%
+% The prevdepth is the depth of the line before the object, the lineskip limit
+% specifies how close the top of the object can come to the bottom of the
+% previous line before \baselineskip is ignored and \lineskip is inserted
+% between the object and the line above it. Lineskip does not come into
+% play unless the first line of the object is high enough to "get too close"
+% (as specified by lineskiplimit) to the line before it. The the prevdepth,
+% lineskip limit, and lineskip optional parameters are not needed for the
+% first object/line on a page (i.e., prevdepth <= -1000pt) where the simplier
+% \topskip spacing rules are in effect.
+%
+% Offset is a manual adjustment that is added to the height calculations of
+% object irrespective of the value of \prevdepth. It is useful when the top
+% baselineskip will result in a noninteger unit height object placement even
+% if the object itself has integral height. e.g., a footnotesize baselineskip
+% is used before the object, thus an offset of, say -3pt, can be given as a
+% correction.
+
+% Common combinations of these parameters include:
+%
+% top baselineskip: (and default values for offset, prevdepth, etc.)
+% \topskip % for objects that appear at the top of a page
+% \maxdimen % always ignore the height of the top line
+% 0pt % always consider any positive height of the top line
+%
+% for objects to appear inline in normal text:
+% top baselineskip = \baselineskip
+%
+% set prevdepth = -1000pt and top baselineskip = 0pt to consider the
+% overall height of the object without any other external skip
+% consideration

+% This is the \@ifmtarg command from the LaTeX ifmtarg package
+% by Peter Wilson (CUA) and Donald Arseneau
+% \@ifmtarg is used to determine if an argument to a command
+% is present or not.
+% For instance:
+% \@ifmtarg{#1}{\typeout{empty}}{\typeout{has something}}
+% \@ifmtarg is used with our redefined \section command if
+% \appendices is invoked.
+% The command \section will behave slightly differently depending
+% on whether the user specifies a title:
+% \section{My appendix title}
+% or not:
+% \section{}
+% This way, we can eliminate the blank lines where the title
+% would be, and the unneeded : after Appendix in the table of
+% contents

+% LaTeX treats environments and commands with optional arguments differently.
+% the actual ("internal") command is stored as \\commandname
+% (accessed via \csname\string\commandname\endcsname )
+% the "external" command \commandname is a macro with code to determine
+% whether or not the optional argument is presented and to provide the
+% default if it is absent. So, in order to save and restore such a command
+% we would have to save and restore \\commandname as well. But, if LaTeX
+% ever changes the way it names the internal names, the trick would break.
+% Instead let us just define a new environment so that the internal
+% name can be left undisturbed.
