DiffEvolutionStrategyType

Description

The DiffEvolutionStrategyType enumeration is used to determine a trial vector generation method.

It is used by the following property:

IDifferEvolutionParams.EvolutionStrategy.

Available Values

Value	Brief description
0	Best1Exp. Exponential strategy of random mutation Best/1.
1	Rand1Exp. Exponential strategy of random mutation Rand/1.
2	RandToBest1Exp. Exponential strategy of random mutation Target-to-best/1.
3	Best2Exp. Exponential strategy of random mutation Best/2.
4	Rand2Exp. Exponential strategy of random mutation Rand/2.
5	Best1Bin. Binomial strategy of random mutation Best/1.
6	Rand1Bin. Binomial strategy of random mutation Rand/1.
7	RandToBest1Bin. Binomial strategy of random mutation Target-to-best/1.
8	Best2Bin. Binomial strategy of random mutation Best/2.
9	Rand2Bin. Binomial strategy of random mutation Rand/2.

Comments

Random mutation strategies:

Best/1. V(i)=X(best)+F*(X(r1)-X(r2)).
Rand/1. V(i)=X(r1)+F*(X(r2)-X(r3)).
Target-to-best/1. V(i)=X(i)+F*(X(best)-X(i))+F*(X(r1)-X(r2)).
Best/2. V(i)=X(best)+F*(X(r1)-X(r2))+F*(X(r3)-X(r4)).
Rand/2.: V(i)=X(r1)+F*(X(r2)-X(r3))+F*(x(r4)-X(r5)).
