Stochastic Programming at IBM Research

Stochastic Programming Software

  • IBM Stochastic Solutions

  • Command-line interface for solving multiperiod stochastic programs in S-MPS format.
  • IBM Stochastic Extensions

  • Library of tools that enable the construction of powerful programs for modeling and solving stochastic programs. Check out the sample drivers and the very informative self-documenting include file.
