I have been maintaining a list of Python optimization packages for a while now on the Coopr Trac pages:  see https://software.sandia.gov/trac/coopr/wiki/Documentation/RelatedProjects .Today, I noticed that if you google for "python optimization packages", this page does not show up right away.  Perhaps Trac pages are index differently?  I'm not sure. Anyway, I thought I'd add this reference here to help others find this list that I'm maintaining...

We are pleased to announce the release of Coopr 3.0 (3.0.4362). Coopr is a collection of Python software packages that supports a diverse set of optimization capabilities for formulating and analyzing optimization models. The following are highlights of this release: - Solvers * More sophisticated logic for solver factory to find ASL and OS solvers * Various solver interface improvements * New Solver results object for efficient representation of variable values * New support for asynchronous progressive hedging - Modeling * Changes in rule semantics to limit rule return values * Changes in the expected order of rule arguments * Constant sums or products can now be used as constraint bounds * Added full support for the !ConstraintList modeling component. - Usability enhancements * More explicit output from runph and runef commands * Added support in runef to write the extensive form in NL format * Add controls for garbage collection in PH - Other * Efficiency impr...
