Generate reference points for structural engineering design problems #1

Hi, How to used IRA-EMO to generate reference points, to be used with preference-based multi-objective optimization algorithm, such as , R-NSGA-II, in solving structural engineering design problems, such as, Spring design, welded beam problems and others. Thank you

Hi @shdotcom,

IRA-EMO does not generate reference points. Instead, you should give them (i.e. an aspiration and a reservation level). Then, the desired number of solutions is generated to represent the part of the Pareto optimal front bounded by the aspiration and the reservation levels given.

Therefore, reference points are not generated by the method but given by the decision maker.

I hope it helps.

Kind regards, Rubén.
