Dear Sage developers,
3 years ago a memory leak in lp solvers was fixed in ticket
http://trac.sagemath.org/ticket/11917. It seems that the problems are back
in Sage 6.3.
The code
while True:
P = MixedIntegerLinearProgram(solver="Coin")
eats several GB within a few seconds!!! The same with solver="Coin", but
not with solver="glpk".
I badly need to run a code for millions of small ILPs, but which
nevertheless are sufficiently big such that "glpk" is useless, "Coin" is a
snail, but gurobi does very well. Is there a quick work around? Doing a
`del P' doesn't help.
Best wishes,
Peter
