This code includes a high performance implementation of the WFG algorithm, used to calculate the hypervolume indicator for a set of non-dominated points.
If you make substantive use of this algorithm, please reference the following paper:
[WFG2010b] Lyndon While, Lucas Bradstreet, and Luigi Barone. A Fast Way of Calculating Exact Hypervolumes. IEEE Transactions on Evolutionary Computation 16(1), 2012
COMPILING:
run make march=processortype, e.g. make march=pentium4
USAGE: where X = 1-3
wfgX FRONTFILE
wfgX FRONTFILE r1 r2 .. rd
Code currently performs minimisation hypervolume calculations relative to the reference point. However, it can be easily transformed to allow maximisation calculations.
FILE FORMAT:
A file can contain any number of fronts, laid out as follows:
0.598 0.737 0.131 0.916 6.745 0.263 0.740 0.449 0.753 6.964 0.109 8.483 0.199 0.302 8.872
0.598 0.737 0.131 0.916 6.745 0.263 0.740 0.449 0.753 6.964 0.109 8.483 0.199 0.302 8.872
Notes:
-
objective values are separated by spaces.
-
one point per line.
-
fronts are separated by #s.
-
all fronts use the same reference point, therefore all points in all fronts must have the same number of objectives.
