Does JGAP support multi objective optimization

Jason De silva
Hi, i am new to Genetic algorithms and i found that jgap is a resourceful library how ever i fail to find the documentation regarding NSGAII which im planning to use to solve a multi objective optimization problem. Please help me out
Thank you

Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.

JGAP doesn´t have NSGA-II. But you can extend it by adding multi-objective logic inside BulkFitnessFunction.evaluate method.

Thanks for the reply is there any examples available to get the hang of it. Eg:- BulkFintessFunctio.evaluate method?

Re: Does JGAP support multi objective optimization

You get all chromosomes through the Population parameter.
 
For each IChromosome, you can access all of its genes, so you can calculate fitness.
 
In single-objective optimization, you then set calculated fitness directly into IChromosome.setFitnessValue(double).
 
In multi-objective optimization you first calculate fitness for each objetive and then cross results from all objectives of all chromosomes to calculate fitness for each chromosome. Then set them all into each chromosome’s setFitnessValue(double) methods.
 
BulkFitnessFunction instance is passed to Configuration.setBulkFitnessFunction method. The rest is like the examples in JGAP’s site.
