Re: GMPL/GLPK display objective function value

[Domingo Alvarez Duarte]

Hello Andrew !

Thanks for reply !

The problem is that the GMPL is not informed/knows anything about the 
warning/divergence in the results and goes blindly.

Te exit code of glpsol also doesn't reflect anything that could be 
detected, only by visual inspection of the output or redirect the output 
and scan it for possible warnings.

Somehow GMPL should have a way to acknowledge situations like these.
