Here is the code of how to put two (or more) algorithms side by side in latex using algorithmic and algorithm packages. (The principle is the same used to put figures side-by-side).
NB: remeber to put [H] as a parameter for \begin{algorithm} (I lost a lot of time trying to understand this very simple thing)
\begin{figure*}[ttt!]
\begin{minipage}[t]{3.15in}
\begin{algorithm}[H]
\caption{Mission-side Greedy}
\label{alg1}
\begin{algorithmic}[1]
\STATE whatever your alg does
\FOR{each mission $M_{j}$ in sorted order}
\STATE do something
\ENDFOR
\end{algorithmic}
\end{algorithm}
\end{minipage}
\hfill
\begin{minipage}[t]{3.15in}
\begin{algorithm}[H]
\caption{Mission-side2 Greedy}
\label{alg2}
\begin{algorithmic}[1]
\STATE whatever your alg does
\FOR{each mission $M_{j}$ in sorted order}
\STATE do something
\ENDFOR
\end{algorithmic}
\end{algorithm}
\end{minipage}
\hfill
\end{figure*}
