Function PGASetEvaluation

Function Documentation

void PGASetEvaluation(PGAContext *ctx, int p, int pop, double val, const double *aux)

Set the evaluation function value for a string to a specified value.

Description

This uses a trick for implementing optional arguments in C. The real function to use is without leading underscore. There is a macro that makes the last argument optional. Also sets the evaluation up to date flag to PGA_TRUE.

Example

Set the evaluation function value of string p in population PGA_NEWPOP to 123.456.

PGAContext *ctx;
int p;
double aux [...];

...
PGASetEvaluation (ctx, p, PGA_NEWPOP, 123.456);

or

PGASetEvaluation (ctx, p, PGA_NEWPOP, 123.456, aux);

Parameters:

  • ctx – context variable

  • p – string index

  • pop – symbolic constant of the population string p is in

  • val – the (user) evaluation value to assign to string p

  • aux – Auxiliary evaluations

Returns:

Sets the evaluation function value of string p and the EvalUpToDate flag via side effect
