Graphics, Figures & Tables ⇒ \caption of figure problem

[kudzu]

Hello,
I use clrscode package and when I put at the same page this second caption of figure

Code: Select all

\begin{figure}[ht]
\begin{codebox}
\Procname{$\proc{Dijkstra}(G,w,s)$}
\li $\proc{Initialize-Single-Source}(G,s)$
\li $S \gets \emptyset $
\li $Q \gets V[G]$
\li \While $Q\neq \emptyset$
\li \Do $u \gets \proc{Extract-Min}(Q)$
\li $S \gets S \cup \{u\}$
\li \For każdy wierzchołek $v\in Adj[u]$
\li \Do $\proc{Relax}(u,v,w)$
\End
\End
\end{codebox}
\caption{Algorytm Dijkstry\label{Dijkstra} \cite{Cormen}}
\end{figure}

\begin{figure}[ht]
\caption{A picture of a tucan.\label{ISS}}
\begin{codebox}
\Procname{$\proc{Initialize-Single-Source}(G,s)$}
\li \For każdy wierzchołek $v\in V[G]$
\li \Do $d[v] \gets \infty$
\li $\pi [v] \gets NIL$
\End
\li $d[s] \gets 0$
\end{codebox}
\end{figure}

I get error

Code: Select all

pdfTex warning (ext4): destination with the same identifier (name{figure.0.3}) has been already used, duplicate ignored

\AtBegShi@Output ...ipout \box \AtBeginShipoutBox   \fi \fi

I read about this something, but still I don't understand how to fix it. In new empty project this code goes ok. I'm using WinEDT 5.3

You must not put the label into the caption itself. You have to place it after the caption.

Code: Select all

\caption[Algorytm Dijkstry \cite{Cormen}]{Algorytm Dijkstry}\label{fig:Dijkstra}

The way you put the label generates the same anchor for the hyperref package thus produces the warning.


Best regards and welcome to the board

It's not working for me. To put the \label in caption I found in some tutorial that says this make us sure the label is after caption.

When I make the code like this, nothing changed.

Code: Select all

\begin{figure}[ht]
\begin{codebox}
\Procname{$\proc{Dijkstra}(G,w,s)$}
\li $\proc{Initialize-Single-Source}(G,s)$
\li $S \gets \emptyset $
\li $Q \gets V[G]$
\li \While $Q\neq \emptyset$
\li \Do $u \gets \proc{Extract-Min}(Q)$
\li $S \gets S \cup \{u\}$
\li \For każdy wierzchołek $v\in Adj[u]$
\li \Do $\proc{Relax}(u,v,w)$
\End
\End
\end{codebox}
\caption{Algorytm Dijkstry}
\end{figure}

\begin{figure}[ht]
\caption{A picture of a tucan}
\begin{codebox}
\Procname{$\proc{Initialize-Single-Source}(G,s)$}
\li \For każdy wierzchołek $v\in V[G]$
\li \Do $d[v] \gets \infty$
\li $\pi [v] \gets NIL$
\End
\li $d[s] \gets 0$
\end{codebox}
\end{figure}

only when I remove the caption from second figure everything is ok. Or it only looks ok.


UPDATE. When I put a lot of text between this two figures and the second of them goes to next pages everything is ok.
So the question: It is not possible to put second figure with caption on the same page or what i should do to make this right?

I don't see the problem. The following works flawlessly for me.

Code: Select all

\listfiles
\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{clrscode}
\usepackage{hyperref}

\begin{document}
  \begin{figure}[!ht]
    \begin{codebox}
      \Procname{$\proc{Dijkstra}(G,w,s)$}
      \li $\proc{Initialize-Single-Source}(G,s)$
      \li $S \gets \emptyset $
      \li $Q \gets V[G]$
      \li \While $Q\neq \emptyset$
      \li \Do $u \gets \proc{Extract-Min}(Q)$
      \li $S \gets S \cup \{u\}$
      \li \For każdy wierzchołek $v\in Adj[u]$
      \li \Do $\proc{Relax}(u,v,w)$
      \End
      \End
    \end{codebox}
    \caption{Algorytm Dijkstry}\label{fig:dijkstry}
  \end{figure}

  Figure \ref{fig:dijkstry} shows an algorithm.

  \begin{figure}[!ht]
    \begin{codebox}
      \Procname{$\proc{Initialize-Single-Source}(G,s)$}
      \li \For każdy wierzchołek $v\in V[G]$
      \li \Do $d[v] \gets \infty$
      \li $\pi [v] \gets NIL$
      \End
      \li $d[s] \gets 0$
    \end{codebox}
    \caption{A picture of a tucan}\label{fig:tucan}
  \end{figure}
\end{document}

Please show the opposite by means of a minimal working example (MWE).

Here comes the MWE.
