Description Usage Arguments Value Author(s)

In this selection mechanism, parents are chosen to produce offspring in the next stage. Three different methods are provided: "twopropselection", "onepropselection" and "tournament"

1	selectparents(originalparents, couplenum, method, fitness, subsetnum = NULL)

`originalparents`	is a casenum * variablenum matrix
`couplenum`	number of couples selected
`method`	the method to select the parents, "twopropselection", "onepropselection" or "tournament"
`fitness`	goodness of fit ~ a casenum * 1 vector , default is AICvalue
`subsetnum`	In method "tournament", we partition the set of chromosomes in generation t into "subsetnum" disjoint subsets
