man PGASetRealInitPercent (Fonctions bibliothèques) - sets the upper and lower bounds for randomly initializing real-valued genes. For each gene these bounds define an interval from which the initial allele value is selected uniformly randomly. With this routine the user specifies a median value and a percent offset for each allele.
NAME
PGASetRealInitPercent - sets the upper and lower bounds for randomly initializing real-valued genes. For each gene these bounds define an interval from which the initial allele value is selected uniformly randomly. With this routine the user specifies a median value and a percent offset for each allele.
INPUT PARAMETERS
- ctx
- - context variable
- median
- - an array containing the mean value of the interval
- percent
- - an array containing the percent offset to add and subtract to the median to define the interval
OUTPUT PARAMETERS
- none

EXAMPLE
Set the initialization routines to select a value for each real-valued gene i uniformly randomly from the interval [i-v,i+v], where $v = i/2$. Assumes all strings are the same length.
PGAContext *ctx; double *median, *percent; int i, stringlen; : stringlen = PGAGetStringLength(ctx); median = (double *) malloc(stringlen*sizeof(double)); percent = (double *) malloc(stringlen*sizeof(double)); for(i=0;i<stringlen;i++) { median[i] = (double) i; percent[i] = 0.5; } PGASetRealInitPercent(ctx, median, percent);
