[Coin-discuss] Cbc crashes for a certain problem

[John J Forrest]

One of the heuristics (feasibility pump) created a small MIP which 
preprocessing found to be infeasible, but did not realize soon enough.

Bug should now be fixed by changes to Cgl/trunk CglPreProcess.cpp (so 
should fix Cbc trunk and devel)

[Coin-discuss] Cbc crashes for a certain problem








Hi,

I've created a ticket https://projects.coin-or.org/Cbc/ticket/16 that 
includes 
a problem that crashes cbc on both trunk and devel, and a patch that fixes 

this. More details in the ticket.

kind regards,
