Chapter I is a study of a variety of finite-stage models, illustrating the wide range of applications of stochastic dynamic programming. Typically, the price change between two successive periods is assumed to be independent of prior history. (eds.) PySP has been used by a number of research groups, including our own, to rapidly prototype and solve difficult stochastic programming problems.

The python interface permits to use the library at a low level. From the per-spective of automatic control, the DP/RL framework comprises a nonlinear and stochastic optimal control problem [9]. Tax calculation will be finalised during checkout. 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. %PDF-1.5 A benchmark problem from dynamic programming is solved with a dynamic optimization method in MATLAB and Python.
