Pareto Assumption for Constrained PSO‐Based Locomotive Resistance Minimization
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 The mechanical resistance of a locomotive is crucial for power consumption. It is desirable to maintain this resistance at a minimum value for energy efficiency under optimal operation conditions. The optimal conditions can be found by particle swarm optimization with constraints.
