@whart222 Looks like you haven't been working in this repo in a while. If you can push me in the right direction, I can try to work up a PR.
@tkralphs Yes, I don't have active funding to support PAO developments. But I've been OOO a bunch the past month, which is the real reason I didn't catch your issue.
I'll take a look at this before the end of next week to help diagnose the issue and give pointers for maintaining the MibS interface.
I tried to run the simple example from the documentation with PAO version 1.0.2 and Pyomo 6.6.2 using MibS 1.2 as the solver using Python 3.9.10 on Ubuntu in WSL.
There was no error, but also just a solution of
(0,0)
. I debugged and everything initially seemed correct. I could actually solve the instance that was created with MibS on the command line from the MPS and AUX files that were output. But when I traced the execution within PAO, it finally ended up on this line and I couldn't really tell what happened.FYI, the output format of the solution has changed a little in MibS 1.2 so I was originally thinking that might be the issue, but it seems that no output was obtained for some reason. I didn't try it on any other platforms. I didn't allocate a huge amount of time to this, just wanted to see if I could make it work :).
Edit: As an aside, I had to install pyutilib manually. It didn't get installed with
pip install pao
.
