Hi,
following example ILP is infeasible in CBC standalone solver but gets value in
CPLEX.
Any idea, thanks in advance?
CBC says:
cullmann at imp:/local/cullmann/build/lpsolve.clpsolve.O0/lpsolve_clpsolve$
../usr/bin/cbc /local/cullmann/git/lpsolve/value_18621.lp
Welcome to the CBC MILP Solver
Version: 2.7
Build Date: Mar 1 2011
command line - ../usr/bin/cbc /local/cullmann/git/lpsolve/value_18621.lp
(default strategy 1)
Continuous objective value is -18621 - 0.00 seconds
Cgl0000I Cut generators found to be infeasible!
Pre-processing says infeasible or unbounded
Greetings
Christoph
