add wfg pareto front

Open gemsanyu opened this issue 5 years ago • 2 comments

the pareto front generating methods are previously commented out also added lexicographical sort so that it can be drawn as line by pyplot for 2-objective

but the visualization is a bit odd at the right end of the 2-D pareto fronts

Thanks for the contribution. Does this generalize to ND too? (can't remember why I commented it out to be honest)

Hey, I just saw your reply. Yes. I now know why the 2D visualization is off (a "wide" gap between points). It's because of the random generation of the PF. Even if I set the size of the PF to 1000, the gap is still visible. However, I haven't really check its effect on the IGD calculation. What do you think?
