4 FAQs about [Benders decomposition improvements power systems]
What is Benders decomposition?
Benders decomposition is a solution method for solving certain large-scale optimization problems. Instead of considering all decision variables and constraints of a large-scale problem simultaneously, Benders decomposition partitions the problem into multiple smaller problems.
When is Benders decomposition effective?
Benders decomposition is particularly effective, if subproblems exhibit a special structure, which can be exploited algorithmically, for example, if the subproblems are maximum flow problems and can be solved analytically or by a tailored sorting algorithm .
Is the Benders decomposition approach effective in solving Integer problems?
Finally, even if they mentioned the method of embedding the Benders decomposition approach in a branch-and-bound procedure, in the subproblems of their experiments there was not an integrality gap and this procedure was not used at all in solving the integer problems. So, no computational results were reported on the efficiency of this procedure.
What are the disadvantages of Benders decomposition?
Drawbacks of the Benders decomposition are closely related to the drawbacks of cutting plane methods, for example, ineffective initial iterations, zigzagging of the lower bound, and slow convergence at the end of the algorithm, in reference to the long convergence tail for cutting plane methods.
