PySP: Modeling and Solving Stochastic Programs in Python Jean-Paul Watson (jwatson sandia.gov) David Woodruff (dlwoodruff ucdavis.edu) William Hart (wehart sandia.gov) Abstract : 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. Mathematical Programming Computation 4 :2, 109-149. Society for Industrial and Applied Mathematics (SIAM) and the Mathematical Programming Society (MPS) (2005), Watson J.P., Woodruff D.L. Pyomo can be used to define abstract and concrete problems, create problem instances, and solve these instances with standard open-source and commercial solvers. 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. The development of PySP was initially motivated by the desire to create generic, database-driven decomposition-based solvers for addressing large-scale, multi-stage stochastic mixed-integer programs; previous implementations in the context of commercial algebraic modeling languages (AMLs) were necessarily problem-specific, and solver customization and parallelization required non-trivial effort. http://www.solver.com, July (2011), GAMS: The General Algebraic Modeling System.
