[Tex/LaTex] Algorithm: ELSEIF problem

algorithms

I want to compile this code in Latex (shown below). I use three libraries. I especially need elseif and \state command and line number.

LaTeX Error:

Command \algorithmicindent already defined.Or name \end... illegal,
see p.192 of the manual.See the LaTeX manual or LaTeX Companion for
explanation.Type H <return> for immediate help....
\newlength{\algorithmicindent}

MWE:

\documentclass[12pt]{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
%\usepackage{algorithmic}

\begin{document}

\begin{algorithm}
\caption{Offloading decision}\label{offloading_decision_pseudocode}
\begin{algorithmic}[1]
\State Known: Smartphone to Edge Cloud and Smartphone to Core Cloud bandwidth,
smartphone to Edge Cloud and smartphone to Core Cloud RTT,
smartphone and Edge/Core Cloud processor speed,
Edge and Core Cloud processing cost
\State Set weights $w1$, $w2$, $w3$ based on user preferences 
\State Estimate $T_{L}$, $T_{R-edge}$, $T_{R-Core}$ (section \ref{estimate_processing_time})
\State Estimate $E_{L}$, $E_{R-edge}$, $E_{R-Core}$ (section \ref{estimate_energy_consumption})
\State Estimate $C_{L}$, $C_{R-edge}$, $C_{R-Core}$ (section \ref{estimate_processing_cost})
\State Compute $P_{s}$, $P_{E}$, $P_{C}$ 
\If {$P_{s}\: is\: maximum $} 
    \State
     \ElseIf {$P_{E}$ is maximum}
\EndIf
\If {$i > \textit{stringlen}$} \Return false
\EndIf
\State $i \gets i-1$.
\State \textbf{goto} \emph{loop}.
\State \textbf{close};
\State $i \gets i+\max(\textit{delta}_1(\textit{string}(i)),\textit{delta}_2(j))$.
\State \textbf{goto} \emph{top}.
\end{algorithmic}
\end{algorithm}
\end{document}

The algpseudocode package defines the command \ElsIf and not \ElseIF
As noticed by @DG' remove \usepackage{algoritmic}

If you use \usepackage{algpseudocode} you don't have to call \usepackage{algortihmicx} explicitly !

\documentclass[12pt]{article}
 \usepackage{algorithm}
 \usepackage{algpseudocode}
 %\usepackage{algorithmic}

\begin{document}

\begin{algorithm}
\caption{Offloading decision}\label{offloading_decision_pseudocode}
\begin{algorithmic}[1]
\State Known: Smartphone to Edge Cloud and Smartphone to Core Cloud bandwidth,
smartphone to Edge Cloud and smartphone to Core Cloud RTT,
smartphone and Edge/Core Cloud processor speed,
Edge and Core Cloud processing cost
\State Set weights $w1$, $w2$, $w3$ based on user preferences 
\State Estimate $T_{L}$, $T_{R-edge}$, $T_{R-Core}$ (section \ref{estimate_processing_time})
\State Estimate $E_{L}$, $E_{R-edge}$, $E_{R-Core}$ (section \ref{estimate_energy_consumption})
\State Estimate $C_{L}$, $C_{R-edge}$, $C_{R-Core}$ (section \ref{estimate_processing_cost})
\State Compute $P_{s}$, $P_{E}$, $P_{C}$ 
\If {$P_{s}\: is\: maximum $} 
    \State
     \ElsIf {$P_{E}$ is maximum}
\EndIf
\If {$i > \textit{stringlen}$} \Return false
\EndIf
\State $i \gets i-1$.
\State \textbf{goto} \emph{loop}.
\State \textbf{close};
\State $i \gets i+\max(\textit{delta}_1(\textit{string}(i)),\textit{delta}_2(j))$.
\State \textbf{goto} \emph{top}.
\end{algorithmic}
\end{algorithm}
\end{document}

The \column command doesn't update the value of \columnwidth that algorithm relies upon for setting its width (and the length of the rules).

Fix: add \setlength{\columnwidth}{\linewidth} at the beginning of an algorithm environment. This is easily done with etoolbox and \AtBeginEnvironment.

\documentclass[a0paper, landscape]{tikzposter} 
\usepackage{graphicx}
\usepackage{color}
\usepackage{tikz}
\usepackage{amsmath,amsfonts,amsthm}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{etoolbox}
\AtBeginEnvironment{algorithm}{%
  \setlength{\columnwidth}{\linewidth}%
}

First of all you are loading both algorithmic and algpseudocode (variant of algorithmicx) which are not compatible.

The syntax you are using is the one of algpseudocode so don't load algorithmic. Moreover, you are using \text and forgot to load amsmath.

Finally, the \Until command has to be used to close a \Repeat statement which is missing in your code.

This is your modified MWE with \Repeat (move it to the right place in the algorithm):

\documentclass{article}
\usepackage{amsmath}
\usepackage{algorithm,algpseudocode}
\begin{document}
\begin{algorithm}
\caption{Resource Allocation Algorithm }
\label{alg:algorithm_sum}
\begin{algorithmic}[1]
\State{Initialization of maximum number of iteration $I_{\text{max}}$, given $\mu^m$ and $\beta^m$ and obtain the intermediate solution for (opt. variables)}
\Repeat
\If{ref. is satisfied}
\State{Convergence =  true}
\Return{opt. variables}
\Else
\State{update $\mu$ and $\beta$ according to ref. and $m=m+1$}
\State{Convergence =  false}
\EndIf
\Until{Convergence = true or $m=I_{\text{max}}$}
\end{algorithmic}
\end{algorithm}
\end{document}

Output:
