                throws InvalidConfigurationException

Initializes the given population by creating individuals for it.

Specified by:

initialize in interface IPopulationCreator

Parameters:

a_pop - the population to initialize

a_types - the type for each chromosome, the length of the array represents the number of chromosomes

a_argTypes - the types of the arguments to each chromosome, must be an array of arrays, the first dimension of which is the number of chromosomes and the second dimension of which is the number of arguments to the chromosome

a_nodeSets - the nodes which are allowed to be used by each chromosome, must be an array of arrays, the first dimension of which is the number of chromosomes and the second dimension of which is the number of nodes

a_minDepths - contains the minimum depth allowed for each chromosome

a_maxDepths - contains the maximum depth allowed for each chromosome

a_maxNodes - reserve space for a_maxNodes number of nodes

a_fullModeAllowed - array of boolean values. For each chromosome there is one value indicating whether the full mode for creating chromosome generations during evolution is allowed (true) or not (false)

Throws:

InvalidConfigurationException - in case of any error
