WitrynaFor questions related to Benders decomposition, a type of optimization algorithm in which certain variables are optimized in a "master problem," the values of those variables are fixed, the remaining variables are optimized in a "subproblem," cuts are generated to be added to the master problem, and the method repeats. Learn more… Top users Witrynatribution of logic-based Benders may be to provide a framework for combining optimization and constraint programming methods. Benders decomposition [7, 17] uses a problem-solving strategy that can be general-ized to a larger context. It assigns some of the variables trial values and ﬁnds the best solution consistent with these values.
