Experiments of a new generation points strategy in a multilocal method. In 9th International Conference on Operations Research and Enterprise Systems, ICORES 2020.

It is important to obtain its solution in the lowest time possible, since the company could benefit from this. Taking this into account, a derivative free method (MCSFilter method) is addressed with a different strategy to generate the initial points to start each local search. The idea is to spread more the points so that the code execution will require a shortest amount of time when compared with the MCSFilter method execution. Some experiments were performed with simple bounds problems, equality and inequality constraint problems, chosen from a set of well known nonlinear problems. The results obtained were encouraging and with the new strategy the method needs less time to obtain the global solution.engPoints generationDerivative-free methodMultistartMCSFilter methodNonlinear optimizationconference paper
