Recombination:
Therefore during the selection and mating process then the GA repeatedly lines up pairs of individuals for reproduction. Hence the next question is how to generate offspring from these parent individuals. Thus this is known like the recombination process and how this is done is largely dependent on the representation scheme being used. However we will look at three possibilities for recombination of individuals represented as bit strings.
Conversely the population will only evolve to be better whether the best parts of the best individuals are combined, thus recombination procedures usually take parts from both parents and place them in the offspring. So however One-Point Crossover recombination process in which a point is chosen at random on the first individual plus the same point is chosen on the second individual. Hence this splits both individuals into a left hand and a right hand side. Further two offspring individuals are then produced through (i) is, taking the LHS of the first and adding it to the RHS of the second (ii) is, through taking the LHS of the second and adding it to the RHS of the first.
