Stochastic Integer Programming Problem
Stochastic Programming is a mathematical framework to help decision-making under uncertainty. Deterministic optimization frameworks like the linear program LP, nonlinear program NLP, mixed-integer program MILP, or mixed-integer nonlinear program MINLP are well-studied, playing a vital role in solving all kinds of optimization problems
In the field of mathematical optimization, stochastic programming is a framework for modeling optimization problems that involve uncertainty.A stochastic program is an optimization problem in which some or all problem parameters are uncertain, but follow known probability distributions. 1 2 This framework contrasts with deterministic optimization, in which all problem parameters are
Stochastic integer programming models arise when the decision variables are required to take on integer values. In most practical situations this entails a loss of convexity and makes the application of decomposition methods problematic. x,w for a small stochastic integer programming problem with two first-stage variables.

By the existence theorem of mixed-integer linear programming this problem then is solvable provided it is bounded. The latter, however, follows from the solvability of the LP relaxation to the mixed-integer program defining t which is a consequence of the primal feasibility implied by 2.7 and the dual feasibility in 2.8.

SIPLIB is a collection of test problems to facilitate computational and algorithmic research in stochastic integer programming. The test problem data is provided in the standard SMPS format unless otherwise mentioned. Where available, information on the underlying problem formulation and known solution is also included.

Multistage stochastic integer programming MSIP combines the difficulty of uncertainty, dynamics, and non-convexity, and constitutes a class of extremely challenging problems. A common formulation for these problems is a dynamic programming formulation involving nested cost-to-go functions. In the linear setting, the cost-to-go functions are convex polyhedral, and decomposition algorithms
Stochastic integer programming problems combine the di-culty of stochastic pro-gramming with integer programming. In this article, we briey review some of the challenges in solving two-stage stochastic integer programming problems, and discuss the research progress towards these challenges. 1 Introduction A standard form for a two-stage
