An implementation of the NSGA-III algorithm in C++

NSGA-III

An implementation of NSGA-III algorithm in C++ according to the article:

• Kalyanmoy Deb, & Himanshu Jain, An Evolutionary Many-Objective Optimization Algorithm Using Reference-Point-Based Nondominated Sorting Approach, Part I: Solving Problems With Box Constraints. IEEE Transactions on Evolutionary Computation, Vol. 18, No. 4, pp. 577–601, Aug 2014. doi:10.1109/TEVC.2013.2281535.

This code was tested using DTLZ and WFG test problems and the obtained results were quite similar to those reported by the authors.

Contributions and bug fixes are welcome.

Demonstration

The demo "src/main_nsga3.cpp" consists of a scalability test of the algorithm NSGA-III by varying the number of objectives from three to ten considering the DTLZ2 problem.

Compile the specific target file:

make Makefile

nsga3's Issues

popsize different to refpoints

nsga3/src/nsga3.h

Line 268 in 00d88fa

I added a print statement

printf(">P:%d R:%lu<", popsize, refepoints.size());

And I have noticed that popsize is 92 while refepoints.size() is 91. Why is that?
