How to change the predetermined command "Require" in "algorithm package".
I want to write input instead of Require
this is my code:
\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage[utf8]{inputenc}
\usepackage{algorithm}
\usepackage{algpseudocode}
\begin{document}
\begin{algorithm}
\begin{algorithmic}
\Require Instead of write Require I want to write \textbf{Input}
\While{$N \neq 0$}\
Output $ =$ Content
\EndWhile\\
\end{algorithmic}
\end{algorithm}
\end{document}
The IEEEtran's documentation suggests:
B. Algorithms
IEEE publications use the
figureenvironment to containalgorithmsthat are not to be a part of the main text flow. Peter Williams’ and Rogerio Brito’salgorithmic.stypackage [24] or Szász János’algorithmicx.stypackage [25] (the latter is designed to be more customizable than the former) may be of help in producing algorithm-like structures (although authors are of course free to use whatever LaTeX commands they are most comfortable with in this regard). However, do not use the floatingalgorithmenvironment ofalgorithm.sty(also by Williams and Brito) oralgorithm2e.sty(by Christophe Fiorio) as the only floating structures IEEE uses arefigures andtables. Furthermore, IEEEtran will not be in control of the (non-IEEE) caption style produced by thealgorithm.styoralgorithm2e.styfloat environments.
So, as suggested, do not use the algorithm floating environment; you can wrap your algorithm inside a figure (or figure*) environment (if a caption is required and the captions are to be IEEEtran compliant) and use the algorithmicx package ; something like this:
\documentclass{IEEEtran}
\usepackage{algpseudocode}
\begin{document}
\begin{figure}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if r is 0}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile\label{euclidendwhile}
\State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\caption{Euclid's algorithm}\label{euclid}
\end{figure}
\end{document}
If no caption is required, then simply don't use the figure environment.
Here's an option that provides feasible output. I've removed the physical numbering in the caption:
\documentclass[10pt,twocolumn]{article}
\usepackage{algorithm,algpseudocode}% http://ctan.org/pkg/{algorithms,algorithmx}
\algnewcommand{\Inputs}[1]{%
\State \textbf{Inputs:}
\Statex \hspace*{\algorithmicindent}\parbox[t]{.8\linewidth}{\raggedright #1}
}
\algnewcommand{\Initialize}[1]{%
\State \textbf{Initialize:}
\Statex \hspace*{\algorithmicindent}\parbox[t]{.8\linewidth}{\raggedright #1}
}
\begin{document}
\begin{algorithm}
\caption{Boosted $K$ Nearest Neighbour}
\begin{algorithmic}[1]
\Inputs{$S={s_i}=\left(x_i,y_i\right)$}
\Initialize{\strut$w_i^0 \gets 0$, $i=1,\ldots,n$ \\ $S_0 \gets S$}
\For{t = 1 to T}
\State $S_t \gets S_{t-1}$
\For{$s_q \in S_t$}
\State $N_q \gets$ k nearest neighbors
\State of $s_q$ using $D(s_q,s_i)$
\State label($s_q$)$=argmax\sum_{s_i \in N_q}D(s_q,s_i)$;
\If{label($s_q$)$\ne y_q$}
\For{$s_i \in N_i$}
\If{$y_i \ne y_q$}
\State $w_{i}^{t} \gets w_{i}^{t} - \lambda/d(x_q,x_i)$;
\Else
\State $w_{i}^{t} \gets w_{i}^{t} + \lambda/d(x_q,x_i)$;
\EndIf
\EndFor
\EndIf
\EndFor
\If{label($s_q$)$=y_q \forall_{s_q}$}
\State break
\EndIf
\EndFor
\end{algorithmic}
\end{algorithm}
\end{document}
A newly-defined \Inputs and (equivalent) \Initialize takes one argument that sets its contents in a \Statex with an indent of \algorithmicindent - the default - to align with the other algorithm elements. The contents is stored in a top-aligned \parbox that fits across 80% of the line. I'm sure you won't need more, but in case you do, that can also be fixed to not cause overfull boxes.
