2 Final Partitioning EA is an iterative process of generations, starting with an initial population in the first generation and iteratively improving the population from one generation to the next. The evolution of the population is driven by three main mechanisms: recombination, mutation, and selection. Recombination and mutation create the necessary diversity, thus facilitating novelty in the population. After recombination and mutation, a selection step takes places to select the best-quality individuals for the next-generation’s population.

An intuitive approach is to combine the conflicting objectives into a single weighted aggregate objective function which is easier to optimize. The optimality of this approach, however, is dependent on the selection of the weight coefficients in the aggregate function. How to choose the best values for these coefficients is a nontrivial task. Alternatively, an effective approach, which is based on evolutionary algorithms (EA), has often been used [41]. The EA-based approach after many generations of crossover and mutation can eventually result in a good set of Pareto-optimal solutions.
