Detailed Description

template<typename IndividualType>
struct shark::ReferenceVectorAdaptation< IndividualType >

Reference vector adaptation for the RVEA algorithm.

This operator is supposed to be applied regularly in the RVEA algorithm to adjust the set of reference vectors to better match a scaled pareto front. See below paper for details: R. Cheng, Y. Jin, M. Olhofer, and B. Sendhoff, “A reference vector guided evolutionary algorithm for many-objective optimization,” IEEE Transactions on Evolutionary Computation, Vol 20, Issue 5, October 2016 http://dx.doi.org/10.1109/TEVC.2016.2519378
