Although stochastic programming is a powerful tool for modeling decision-making under uncertainty, various impediments have historically prevented its wide-spread use. We simultaneously address both of these factors in our PySP software package, which is part of the Coopr open-source Python repository for optimization; the latter is distributed as part of IBM’s COIN-OR repository. One factor involves the ability of non-specialists to easily express stochastic programming problems as extensions of their deterministic counterparts, which are typically formulated first. and some commonly used objects in stochastic programming.

By leveraging the combination of a high-level programming language (Python) and the embedding of the base deterministic model in that language (Pyomo), we are able to provide completely generic and highly configurable solver implementations. Intricate, configurable, and parallel decomposition strategies are frequently required to achieve tractable run-times on large-scale problems. 8(4), 355–370 (2011), Woodruff D.L., Zemel E.: Hashing vectors for tabu search.
