Description
of the method |
The mono-objective optimization method SQP can solve multi-objective optimization problem using variable weighted sum of objectives. Then, the Pareto front can be obtained using several values of the weight α taken from [0,1]. Therefore, if the initial point is far from the global solution, the SQP algorithm can be trapped in local optima. To overcome this disadvantage, SQP should be restarted with several initial points in order to compute each Pareto front point.
