The jMetal project is structured in four Maven subprojects: jmetal-core, jmetal-algorithm, jmetal-problem, and jmetal-exec. Dependending on the requirements of your project, you may need to import the needed dependences for...

Currently the elitism in the single objective GAs is implemented in the replacement method, where the two best solutions of the current population are added to the offspring one. If...

This is a really interesting issue, which has been "sleeping" since we started with jMetal 5. > But isn't it too much? It seems to me that variables should be...

You can find examples here: https://github.com/jMetal/jMetalPy/blob/main/jmetal/problem/multiobjective/unconstrained.py Some of the problems are defined in https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=996017

About using equality constraints, I have never worked with problems having such kind of constraints, but I think that you can convert them into inequality constraints by using an epsilon...

I remember that someone mentioned that alternative (with a very low value of e, e.g., 0.00000001) in a paper. I don't know how effective it can be, but it is...

Hi @magal1337 I recevied your message with the codes but I would need to know how to instantiate the problem: ``` if __name__ == "__main__": problem = RoutesOpt() algorithm =...

I would suggest you to follow the "Starting in Two Minutes" guide: http://docs.sonarqube.org/display/SONAR/Get+Started+in+Two+Minutes Once you have the software installed, the sonar-project.properties is in the root directory of the project, so...

Why are you using a population size of 100000 solutions? Just think that the goal of multi-objective optimization usually is to give the decision maker a representative set of solutions...

> 100k solutions is not much in terms of memory, so rising an out of memory error if we run only that is crazy. I agree with this. > It...
