pyomo / pysp Goto Github PK

In an effort to simplify / standardize configuration / options in Pyomo, we should ensure that we only use a single configuration management system. The customizations / overrides in PySPConfigBlock and PySPConfigValue should be reviewed and, if appropriate, merged into pyutilib.misc.config. PySP should then directly use the pyutilib.misc.config system.

Someone (maybe me), should take a look at the termination about from runph, particularly expectations and solutions associate with xhat. I think it there is output for the xhat of the last iteration that is not clearly labelled as such. And, anyway, I don't know why anyone would want that. What they should want is the best xhat and its assocated costs. Those are what are used to compute the gap.

A user points out that the phsolutionwriter plugin writes the last solution seen, which pretty much no one wants. There should be a mechanism for the bounds plugin to keep the best x-hat and then print that solution at the end. This would be a bit of a change because presently we just keep all the xhat objs and then figure out who was the best at the end; we would have to change to keeping a best-so-far unless we wanted to keep all xhats
