Bug 75

Summary: DBM corruption of the diagonal in extrapolation algorithm
Product: UPPAAL Reporter: Gerd Behrmann <behrmann>

Status: CLOSED FIXED    
Severity: normal    
Priority: P2

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 on the 8th of December 2003.
