algorithm2enumbering
I am trying to define a new environment that uses the algorithm environment from algorithm2e. I want to use a separate caption counter for this new environment. As of now, this is what I have, but I don't know how to \def or \renewcommand the caption variable with the hdps counter?
\newcounter{hdps}
\newenvironment{asm}{%
\stepcounter{hdps}%
\renewcommand*{\algorithmcfname}{ASM Spec.}%
\begin{algorithm}}
{%
\def\thealgocf{}%
\end{algorithm}}
Help is much appreciated.
You could just force the counter associated with that environment.
Note that, in typical LaTeX fashion, counters are incremented just before they're used. So, in order to force the algorithm to start as Algorithm 3 (say), one would set the associated counter to 2. The counter used by algorithm2e for the algorithm environment is algocf (named after the author, Christophe Fiorio, I presume). So, using
\setcounter{algocf}{2}
immediately before using the algorithm environment would set the following algorithm as Algorithm 3.
The following example is taken from the algorithm2e documentation:
\documentclass{article}
\usepackage[ruled]{algorithm2e}% http://ctan.org/pkg/algorithm2e
\begin{document}
\setcounter{algocf}{2}% Modify counter of algorithm
\begin{algorithm}

\KwData{$G=(X,U)$ such that $G^{tc}$ is an order.}
\KwResult{$G’=(X,V)$ with $V\subseteq U$ such that $G’^{tc}$ is an
interval order.}
\Begin{
$V \longleftarrow U$\;
$S \longleftarrow \emptyset$\;
\For{$x\in X$}{
$NbSuccInS(x) \longleftarrow 0$\;
$NbPredInMin(x) \longleftarrow 0$\;
$NbPredNotInMin(x) \longleftarrow |ImPred(x)|$\;
}
\For{$x \in X$}{
\If{$NbPredInMin(x) = 0$ {\bf and} $NbPredNotInMin(x) = 0$}{
$AppendToMin(x)$}
}
\nl\While{$S \neq \emptyset$}{\label{InRes1}
\nlset{REM} remove $x$ from the list of $T$ of maximal index\;\label{InResR}
\lnl{InRes2}\While{$|S \cap ImSucc(x)| \neq |S|$}{
\For{$ y \in S-ImSucc(x)$}{
\{ remove from $V$ all the arcs $zy$ : \}\;
\For{$z \in ImPred(y) \cap Min$}{
remove the arc $zy$ from $V$\;
$NbSuccInS(z) \longleftarrow NbSuccInS(z) - 1$\;
move $z$ in $T$ to the list preceding its present list\;
\{i.e. If $z \in T[k]$, move $z$ from $T[k]$ to
$T[k-1]$\}\;
}
$NbPredInMin(y) \longleftarrow 0$\;
$NbPredNotInMin(y) \longleftarrow 0$\;
$S \longleftarrow S - \{y\}$\;
$AppendToMin(y)$\;
}
}
$RemoveFromMin(x)$\;
}
}

Switch to the subcaption package.
The problem comes from a bad interaction between the H placement specifier from the float package and subfig, as the following reduced example shows:
\documentclass[a4paper]{scrreprt}
\usepackage[demo]{graphicx}
\usepackage{float}
\usepackage{subfig}
\begin{document}
\begin{figure}[H]
\centering
\subfloat[test]{\includegraphics[width=3cm]{image1}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image2}}
\caption{First part of a continued float}
\end{figure}
\begin{figure}[H]
\centering
\ContinuedFloat
\subfloat[test]{\includegraphics[width=3cm]{image3}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image4}}
\caption{Second part of the continued float}
\label{dr:s:ist:som}
\end{figure}
\begin{figure}[H]
\centering
\subfloat[test]{\includegraphics[width=3cm]{image5}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image6}}
\caption{Another independent figure with subfigures}
\label{dr:s:ist:win}
\end{figure}
\end{document}
Removing the H placement specifier fixes the problem with the subfigures, but creates another one:
\documentclass[a4paper]{scrreprt}
\usepackage[demo]{graphicx}
\usepackage{float}
\usepackage{subfig}
\begin{document}
\begin{figure}
\centering
\subfloat[test]{\includegraphics[width=3cm]{image1}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image2}}
\caption{First part of a continued float}
\end{figure}
\begin{figure}
\centering
\ContinuedFloat
\subfloat[test]{\includegraphics[width=3cm]{image3}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image4}}
\caption{Second part of the continued float}
\label{dr:s:ist:som}
\end{figure}
\begin{figure}
\centering
\subfloat[test]{\includegraphics[width=3cm]{image5}}\quad
\subfloat[test]{\includegraphics[width=3cm]{image6}}
\caption{Another independent figure with subfigures}
\label{dr:s:ist:win}
\end{figure}
\end{document}
Now, the subfigures are correctly numbered, but figures are not. The definitive solution is to switch to the subcaption package (you can even use again the H specifier). In the following example I used \subcaptionbox, but the package offers also a subfigure environment:
\documentclass[a4paper]{scrreprt}
\usepackage[demo]{graphicx}
\usepackage{float}
\usepackage{subcaption}
\begin{document}
\begin{figure}[H]
\centering
\subcaptionbox{test}{\includegraphics[width=3cm]{image1}}\quad
\subcaptionbox{test}{\includegraphics[width=3cm]{image2}}
\caption{First part of a continued float}
\end{figure}
\begin{figure}[H]
\centering
\ContinuedFloat
\subcaptionbox{test}{\includegraphics[width=3cm]{image3}}\quad
\subcaptionbox{test}{\includegraphics[width=3cm]{image4}}
\caption{Second part of the continued float}
\label{dr:s:ist:som}
\end{figure}
\begin{figure}[H]
\centering
\subcaptionbox{test}{\includegraphics[width=3cm]{image5}}\quad
\subcaptionbox{test}{\includegraphics[width=3cm]{image6}}
\caption{Another independent figure with subfigures}
\label{dr:s:ist:win}
\end{figure}
\end{document}
The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

You could use something like this:
EDIT: of course, this approach will only work as expected if
\captionis used consistently in thealgorithmandasmenvironments.
