PGASetRealInitRange (2)

For each gene these bounds define an interval from which the initial allele value is selected uniformly randomly. The user specifies two arrays containing lower and bound for each gene to define the interval. This is the default strategy for initializing real-valued strings. The default interval is $[0,1.0]$ for each gene.

ctx

- context variable

min

- array containing the lower bound of the interval for each gene

mac

- array containing the upper bound of the interval for each gene

none

Set the initialization routines to select a value for each real-valued
gene i uniformly randomly from the interval [-10.,i]
Assumes all strings are of the same length.
