SELection by Roulette Wheel Selection
This function performs selection with Roulette wheel selection.
This function selects a given number of individuals Nsel from a
population. FitnV is a column vector containing the fitness
values of the individuals in the population.
Syntax: NewChrIx = selrws(FitnV, Nsel)
Input parameters:
FitnV - Column vector containing the fitness values of the
individuals in the population.
Nsel - Number of individuals to be selected
Output parameters:
NewChromIx- Column vector containing the indexes of the selected
individuals relative to the original population, shuffeld.
The new population, ready for mating, can be obtained
