Benjamin McCann updated MATH-246:
---------------------------------
Attachment: SimplexSolverTest.patch
SimplexTableau.patch
Hi Luc,
What you did was fine. It exposed a bug, which I've attached a patch for.
In the large test, there were multiple variables that could have taken a given
value. For example, when we solved the problem let's say it turned out that
one of two cases could be true:
x2 = 0 and x3 = 49
x2 = 49 and x3 = 0
In this ambiguous case, I was setting x2 and x3 to 49. The patch makes it so
that we just choose the first variable when settings its value from the
solution.
