A direct way to solve the problem is by an efficient optimization method called dynamic programming.
Secondly, the optimization method used might not be guaranteed to converge when far away from a local minimum.
These various measures of the step response usually conflict with one another, requiring optimization methods.
It is used as a benchmark for many optimization methods.
During that time the mining industry was developing optimization methods on their own.
Several new optimization methods have been created (optvgmrf and optvgm32).
In the 1960s and early 1970s, evolutionary algorithms became widely recognized as optimization methods.
The first strategy is based on correlated sampling together with deterministic optimization methods.
Typical optimization methods can not deal with such types of problem.
It can be quite effective to combine GA with other optimization methods.
