I earlier mentioned that I developed a plugin framework within my PyUtilib software.  This is now called the PyUtilib Component Architecture (PCA).  The PCA is derived from the Trac component architecture, and it supports advanced features like nonsingleton components, namespaces and caching of component interactions. The PCA includes an independent, self-contained framework core that can be easily integrated into other applications, as well as a variety of extension packages with commonly used components. See The PyUtilib Component Architecture for further details.

Coopr is a collection of Python optimization-related packages that supports a diverse set of optimization capabilities for formulating and analyzing optimization models. The following are key Coopr capabilities that are driving Coopr development: Pyomo: Formulate algebraic models within Python's modern programming language PySP: Generic solvers for stochastic programming problems COLIN: Scripts that simplify IO between optimizers and black-box applications SUCASA: Customize MIP solvers to expose model structure to the MIP solver engine See https://software.sandia.gov/trac/coopr/wiki/GettingStarted for instructions for getting started with Coopr. An installation script, coopr_install, is provided to simplify the installation of Coopr packages along with the third-party Python packages that they depend on. This installer can also automatically install extension packages from Coin Bazaar. See http://groups.google.com/group/coopr-forum/topics for online discussions of Coopr. Two ...
