# PGASetFitnessMinType(1)

sets the type of algorithm used if a minimization problem is specified to determine how values are remapped for maximization.

## NAME

PGASetFitnessMinType - sets the type of algorithm used if a minimization problem is specified to determine how values are remapped for maximization.

## DESCRIPTION

Valid choices are PGA\_FITNESSMIN\_RECIPROCAL and PGA\_FITNESSMIN\_CMAX to do the mapping using the reciprocal of the evaluation function, or by subtracting the worst evaluation function value from each evaluation function value, respectively.  The default is PGA\_FITNESSMIN\_CMAX

## INPUT PARAMETERS

- ctx

  \- context variable

- fitness\_type

  \- symbolic constant to specify fitness minimization type

## OUTPUT PARAMETERS

- none

  ## SYNOPSIS

```
#include "pgapack.h"
void  PGASetFitnessMinType(ctx, fitness_type)
PGAContext *ctx
int fitness_type
```

## LOCATION

fitness.c

## EXAMPLE

```
Example:
PGAContext *ctx;
:
PGASetFitnessMinType(ctx, PGA_FITNESSMIN_CMAX);
```
