In LaTeX, the hyperref
package can be challenging to work with. It is well known that the hyperref
package must be loaded last, BUT when using the algorithm
package as well things get tricky. algorithm
must be loaded after hyperref
BUT, doing the following error if figures are used at the same time with pdfTeX:
ERROR: pdfTeX warning (ext4): destination with the same identifier (name{figure.1})
The solution is to load the float
package (which is normally loaded by other more high-level packages) before hyperref
like so:
\usepackage{amsmath,amsymb,graphicx,subfigure,etc.,etc.}
\usepackage{float}
\usepackage{hyperref}
\usepackage{algorithm}
The other solution is to not use pdfLaTeX, and use regular LaTeX instead.
