ON-LINE DESIGN OF WATER RESERVOIR POLICIES BASED ON INFLOW PREDICTION [PDF]
IFAC Proceedings Volumes, 2008 Abstract Stochastic Dynamic Programming (SDP) is the method most extensively adopted to design release policies for water reservoir networks. However, it suffers of the well known “curse of dimensionality”, which actually limits its applicability to small reservoir networks.
