Parent Selection is the process of selecting parents which mate and recombine to create off-springs for the next generation. A fixed point is chosen on the wheel circumference as shown and the wheel is rotated.
Rank Selection also works with negative fitness values and is mostly used when the individuals in the population have very close fitness values this happens usually at the end of the run. The selection of the parents depends on the rank of each individual and not the fitness.
Consider a circular wheel. Previous Page Print Page.
For the second parent, the same process is repeated. Also, such a setup encourages the highly fit individuals to be chosen at least once. Therefore, the probability of choosing an individual depends directly on its fitness. Next Page. Parent selection is very crucial to the convergence rate of the GA as good parents drive individuals to a better and fitter solutions. This leads to each individual having an almost equal share of the pie like in case of fitness proportionate selection as shown in the following image and hence each individual no matter how fit relative to each other has an approximately same probability of getting selected as a parent. In this strategy we randomly select parents from the existing population. It is clear that a fitter individual has a greater pie on the wheel and therefore a greater chance of landing in front of the fixed point when the wheel is rotated. Therefore, such a selection strategy applies a selection pressure to the more fit individuals in the population, evolving better individuals over time. However, care should be taken to prevent one extremely fit solution from taking over the entire population in a few generations, as this leads to the solutions being close to one another in the solution space thereby leading to a loss of diversity. This taking up of the entire population by one extremely fit solution is known as premature convergence and is an undesirable condition in a GA. Stochastic Universal Sampling is quite similar to Roulette wheel selection, however instead of having just one fixed point, we have multiple fixed points as shown in the following image. The same process is repeated for selecting the next parent. However, every individual in the population is ranked according to their fitness. Fitness Proportionate Selection is one of the most popular ways of parent selection. In a roulette wheel selection, the circular wheel is divided as described before. In this, we remove the concept of a fitness value while selecting a parent. The wheel is divided into n pies , where n is the number of individuals in the population. Therefore, fitter individuals have a higher chance of mating and propagating their features to the next generation. Previous Page.
