I'm wondering what software implements specialized methods for stochastic integer programs. I've found SPLIOR implements methods for simple integer recourse, and PySP includes progressive hedging algorithms. I know there are others that write the deterministic equivalent and allow you to give the DE to an existing IP solver. Is there anything else? I'm working on implementing the D^2 and D^2BAC algorithms, first described in "The C3 Theorem and a D2 Algorithm for Large Scale Stochastic Integer Programming: Set Convexification" (Sen and Higle, Math Programming, 2005). I'd especially be interested in an existing implementation of these algorithms. Lewis Ntaimo's dissertation does an excellent job of describing them in detail (including pseudocode!), but the implementation is not so trivial. Thanks! asked 01 Nov '11, 23:01 Luis de la T... 
LINGO 13 can solve stochastic integer programs using DEP (with Monte Carlo sampling). It also offers nested Benders' decomposition for solving stochastic linear programs. The negative point is that it's not free. DECIS available through GAMS can solve stochastic (non)linear programs through various techniques using other solvers such as CPLEX. However, as far as I know, it cannot solve integer programs as you cannot define stage variables to be discrete. However, looking at its user guide, which describes its solution strategies, might give you some ideas. Finally, it seems that Solver Foundation has some stochastic programming features, however the MSDN is not very well documented about this and I couldn't find any details about types of problems it can solves or types of algorithms it uses. Update: As of March 2012, GAMS is offering solution of stochastic programs based on specialized model implementation (EMP reformualtion framework) using different solvers such as DE, DECIS, and LINDO. answered 02 Nov '11, 15:31 Ehsan ♦ I think I read somewhere that Solver Foundation can solve 2stage recourse problems, but I might be wrong.

See ddsip http://www.neosserver.org/neos/solvers/slp:ddsip/LP.html which uses dual decomposition. answered 02 Nov '11, 21:24 Shabbir Ahmed 
There is an implementation with me which has been reported in Yuan and Sen's Enhanced D^2BAC paper. We will soon have an general integer version also. For sampling, you may take a look at the SD Project (for continuous SP) https://sites.google.com/a/datadrivendecisions.org/www/ answered 12 Jan '12, 01:18 Yunwei Fantastic! Is there a mailing list I can get on for release announcements of your code, or can you post on ORExchange when the general integer version is released?

AIMMS, which comes with free academic license, provide some methods for solving stochastic programming problem (I'm sorry I do not know much in this field) http://www.aimms.com/operationsresearch/mathematicalprogramming/stochasticprogramming answered 04 Nov '11, 01:05 NVA 
OptQuest uses tabu search (a metaheuristic) and can solve stochastic MINLP's. It is a commercial package, available directly from Opttek, or with a few other Monte Carlo simulation packages. For example, Oracle Crystal Ball can perform simulation and stochastic optimization within Excel and has a friendly GUI.

Thanks for the help. There isn't really a clear answer to mark as the 'correct' one but both of these help.
