Webbut unlike previous progressive hedging approaches for SMIP, our al-gorithm can be shown to converge to the optimal Lagrangian dual value. The key improvement in the new algorithm is an inner loop of optimized linearization steps, similar to those taken in the clas-sical Frank-Wolfe method.

WebProgressive hedging (PH) is a classical decomposition algorithm for solving multistage stochastic problems. However, due to the exponentially growing model size of real-world enterprise-wide optimization problems, critical issues arise when implementing PH in practice. In this work, we propose a novel PH-based algorithm to address integrated … WebThe progressive hedging algorithm (PHA) has emerged as an e ective method for solving multi-stage stochastic programs, particularly those with discrete decision variables in … Webincompatible with the progressive hedging algorithm because they lack the scenario-wise separability of an expected value on which that scheme relies. Here we demonstrate in Section 3 that the progressive hedging algorithm can be applied despite that seeming obstacle through a restatement which makes use of a formula in [1, 2]. imp hors connexion
