# PGASetIntegerInitRange(3)

sets a flag to tell the initialization routines to set each integer-valued gene to a value chosen randomly from the interval given by an upper and lower bound. No string initialization is done by this call.

## NAME

PGASetIntegerInitRange - sets a flag to tell the initialization routines to set each integer-valued gene to a value chosen randomly from the interval given by an upper and lower bound.  No string initialization is done by this call.

## INPUT PARAMETERS

- ctx

  \- context variable

- min

  \- array of lower bounds that define the interval the gene is initialized from

- max

  \- array of upper bounds that define the interval the gene is initialized from

## OUTPUT PARAMETERS

- none

  ## SYNOPSIS

```
#include "pgapack.h"
void  PGASetIntegerInitRange(ctx, min, max)
PGAContext *ctx
int *min
int *max
```

## LOCATION

integer.c

## EXAMPLE

```
Set the initialization routines to select a value for gene i
uniformly randomly from the interval [0,i].  Assumes all strings
are of the same length.
PGAContext *ctx;
int *low, *high, stringlen, i;
:
stringlen = PGAGetStringLength(ctx);
low  = (int *) malloc(stringlen*sizeof(int));
high = (int *) malloc(stringlen*sizeof(int));
for(i=0;i<stringlen;i++) {
low[i]  = 0;
high[i] = i
}
PGASetIntegerInitRange(ctx, low, high);
```
