%
% 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.

% For example, 10pt text uses an interword glue of:

% 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:

% **** 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

% environments.

% 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.

% \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
