bbo (version 0.2)

bbo.control: Control various aspects of the BBO implementation

Description

Allow the user to set some characteristics of the Biogeography-based optimization algorithm implemented in bbo.

Usage

bbo.control(pModify = 1, pMutate = 0.3, KEEP = 5, 
					popSize = 20, 
					maxGen = 20, 
					numVar = 2, 
					orderDep = TRUE)

Arguments

pModify

habitat modification probability, between 0 and 1; default = 1

pMutate

mutation probability; default = 0.3

KEEP

elitism parameter: how many of the best habitats to keep from one generation to the next; default = 5

popSize

population size (i.e., number of candidate solutions for every generation) default = 20. Kindly make sure that KEEP is never greater than popSize and not

maxGen

number of generations; default = 20

numVar

number of variables in each population member (i.e., problem dimension); default = 2

orderDep

TRUE/FALSE; whether order of the parameters of the habitat is to be maintained; default = TRUE

Value

Returns a list with all the BBO algorithm parameters set
