Resolve IPOPT interface issues
|Reported by:||wehart||Owned by:||wehart|
I just downloaded ipopt from COIN-OR, and ran it on my PC. I get the following output:
C:\coopr>bin\pyomo.exe --solver=asl --solver-options='solver=ipopt' model.py model.dat [ 0.00] Setting up Pyomo environment [ 0.00] Applying Pyomo preprocessing actions [ 0.01] Creating model [ 0.13] Applying solver [ 0.42] Processing results Number of solutions: 1 Solution Information Gap: <undefined> Status: unknown Solver results file: results.yml [ 0.46] Applying Pyomo postprocessing actions [ 0.46] Pyomo Finished
The final value isn't being captured in the results object. But, I'm not sure why.
