Revision 1257 - (show annotations) (download) (as text)
Sun Jan 28 01:30:08 2007 UTC (12 years, 9 months ago) by johnpye
Original Path: trunk/test.py
File MIME type: text/x-python
File size: 33618 byte(s)
Fixed the bounding problem in Slv9.
Added python test cases for all of the models in Vicente's thesis.
Will now add these tests to buildbot.
