Threshold accepting Metaheuristics : a move must no deteriorate the evaluation more than the current threshod : the threshold goes down linearly from thresholdinit to 0
ThresholdAccepting::ThresholdAccepting | ( | double | maxthreshold, |
int | walklength | ||
) |
constructor : two arguments : maxthreshold the initial threshold and walklength , it computes a constant step for lowering the threshold

the threshold is lowered by delta
Reimplemented from Metaheuristic.
