Abstract:The optimal pivoting path of the simplex method is crucial for solving linear programming problems. This study proposes a new method to provide the optimal pivot and all the corresponding best pivoting paths using the Monte Carlo tree search (MCTS). First, we propose SimplexPseudoTree to transfer the simplex method into tree search mode while avoiding repeated basis variables. Based on the SimplexPseudoTree, we propose four reinforcement learning (RL) models with two actions and two rewards to make the Monte C… Show more
