Function PGASetSumConstraintsFlag

Function Documentation

void PGASetSumConstraintsFlag(PGAContext *ctx, int n)

Configure if constraints are summed for minimization or use nondominated sorting for optimization.

Description

This only has an effect if the NSGA-II or NSGA-III replacement scheme is configured. In that case, using nondominated sorting for constraint optimization can be turned on by this option. By default constraints are summed and the sum in minimized. This is also done if no NSGA replacement scheme is in use. If summing is disabled by setting this configuration to PGA_FALSE, constraints are minimized using nondominated sorting. Note that nondominated sorting for constrains may not work very well on many problems.

Example

PGAContext *ctx;

...
PGASetSumConstraintsFlag (ctx, PGA_FALSE);

Parameters:

  • ctx – context variable

  • n – PGA_TRUE or PGA_FALSE

Returns:

None
