Detailed Description

template<class EOT>
class eoPBILAdditive< EOT >

Distribution Class for PBIL algorithm (Population-Based Incremental Learning, Baluja and Caruana 96)

This class implements an extended update rule: in the original paper, the authors used

p(i)(t+1) = (1-LR)*p(i)(t) + LR*best(i)

here the same formula is applied, with some of the best individuals and for some of the worst individuals (with different learning rates)
