Required Arguments
int n
(Input)
The number of individuals to add to the population.
Imsls_f_individual
*individual[]
(Input)
An array of pointers to n individuals.
Imsls_f_population
*population
(Input/Output)

Optional Arguments
IMSLS_PRINT
(Input)
By default, summary statistics are not printed. This option
turns on printing of the summary statistics for the new population.
IMSLS_FITNESS, float fitness[]
(Input)
An array of length n containing the
fitness values for the individuals added to the population. fitness[i] is the
fitness for the i-th individual.
IMSLS_FITNESS_FCN, float
fitness(Imsls_f_individual
*individual) (Input)
The fitness function calculated for
individual. If
this is supplied, fitness values are calculated for each individual and included
within the expanded population data structure. Otherwise they are set to
zero.
IMSLS_FITNESS_FCN_WITH_PARMS, float
fitness(Imsls_f_individual *individual,
void
*parms), void *parms, (Input)
The fitness function calculated for
individual. If
this is supplied, fitness values are calculated for each individual and included
in the expanded population data structure. The parameters in parms are passed to
the function.
Description
Function imsls_f_ga_grow_population grows an existing population by adding new individuals. The chromosome data structure of the individuals and the population must be identical. Fitness values for the new population are set to zero unless the fitness function is supplied using the optional arguments IMSLS_FITNESS_FCN or IMSLS_FITNESS_FCN_WITH_PARMS.
Fitness values for the new individuals can also be supplied using optional argument IMSLS_FITNESS.
