Algorithms in Latex

For example:

\begin{algorithm}[H]
\KwIn{sane people and photos}
\KwOut{bebo addicts}

\ForEach{bebo user}{
\If{on the internet}{
waste time on bebo\;
}
}
\end{algorithm}

So it keeps scope with the curly brackets just like C/C++/C#/Java, which is quite neat. Compare this to the older algorithm packages in Latex like algorithmic and algorithm, which force you to put in \if and \endif to keep scope, and anytime you want to put in a command you need to put \state at the beginning of the line. So converting code this way is more of a pain. It also doesnt look as good.

Heres a more complex example:

\begin{algorithm}[H]
\SetLine
\KwIn{Set of tasks and processors}
\KwOut{Mapping of tasks to processors}

\ForEach{Task $i$}{
\ForEach{Processor $j$}{
Calculate EW($i$,$j$)\;
\If{EW($i$,$j$) $\le$ EW($a$,$b$)}{
$a$ = $i$\;
$b$ = $j$\;
}
}
}
\While{Unscheduled tasks remaining}{
\ForEach{Processor $j$}{
Calculate FT($a$,$j$)\;
\If{FT($a$,$j$) $\le$ FT($a$,$c$)}{
$c$ = $j$\;
}
}
Schedule(Task $a$ on Processor $c$) \;
}
\caption{The Min-Error (MinE) algorithm with an earliest first heuristic}
\label{alg:mine}
\end{algorithm}

and another example.

The verdict

The algorithm2e package is definatly the way to go if your doing algorithms in Latex.
