Hi,
As Jeffrey say:
"Sometimes small changes in numerics can make a big difference in how
the branches of an MIP problem are explored"
The FPU Control Word directly impact how glpk will explore branches.
It can be different by thread. The default value is not the same if you
are using visual studio, gcc or java ...
GLPK don't set the FPU control word.

Hi,
I'm using GLPK in one project and the time taken to compute is longer on
a more powerful computer. Does it make any sense to you ?
I don't have any clues about how to debug it. I would really appreciate
tips to diagnose the problem.
