Description Gerd Behrmann 2003-12-20 00:51:08 CET
In certain cases the extrapolation algorithm can corrupt the diagonal of the
DBMs. This can lead to missed inclusion check and thus degraded performance, but
it is believed that when Uppaal terminates, it produces the correct result.

A fix was checked into CVS by adavid@cs.auc.dk on the 8th of December 2003.
