[Coin-discuss] Cbc 2.2 reports integer-infeasible

[Sebastian Nowozin]

Hello everybody,

I filed a ticket for Cbc
https://projects.coin-or.org/Cbc/ticket/58

The observed behaviour is strange and might be an issue related to the 
MPS standard or Cbc/Cgl.  Cplex 9.1, Cbc 2.2 and Blis report the model 
as integer-infeasible, but GLPK 4.27, Xpress MP, and SCIP report an 
integer-feasible solution; see the bug report.

Thanks,
Sebastian
