Lei & Tingzhi Adaptation Function

Description

This adaptation function proposed by Lei & Tingzhi (1994) is an adaptation function that takes into account the cooperation of individuals.

Usage

leitingzhi(fitvals, cxpc, cxpc2, 
                      mutpm, mutpm2, adapa, adapb, ...)

Arguments

`fitvals`	A vector. Fitness values of current generation
`cxpc`	Crossover rate for adaptation. 0 <= cxpc <= 1. default is 0.9
`cxpc2`	Crossover rate for adaptation. 0 <= cxpc2 <= 1. default is 0.5
`mutpm`	Mutation rate for adaptation. 0 <= mutpm <= 1. default is 0.05
`mutpm2`	Mutation rate for adaptation. 0 <= mutpm2 <= 1. default is 0.2
`adapa`	Adaptation threshold for average of fitness values. 0 <= adapa <= 1. default is 0.7
`adapb`	Adaptation threshold for minimum of fitness values. 0.5 <= adapb <= 1. default is 0.5
`...`	Further arguments passed to or from other methods.

Value

`pc`	Crossover rate
`pm`	Mutation rate
