Hello everybody!

I'm a student at Paris Dauphine University and i'm using GLPK to solve
MIP problems (as part of my master thesis : Operational Research and
Decision Aiding). 

When i solve my MIP problem with these two basic API Routines :

glp_simplex(mip, NULL);
glp_intopt(mip, NULL);

this message is shown on the screen:

OPTIMAL SOLUTION FOUND (Optimal solution to LP rekaxation)
other comments...
INTEGER OPTIMAL SOLUTION FOUND

The problem is the fact that this optimal integer solution is not
integer

Any help or idea?

Thanks in advance!
