We investigated two major families of algorithms for the multi-objective optimization: evolutionary andswarm intelligence-based optimization approaches. Non-dominated Sorting Genetic Algorithm II (NSGA-II) andmulti-objective particle swarm optimization (MOPSO) algorithms are biology inspired and are population-based asuse a set of solutions which evolve within the search space. These approaches employ different strategies andcomputational effort; therefore, a comparison of their performance is needed. This paper presents the applicationand performance comparison of NSGA-II and one variant of the MOPSO, namely MOPSO-CD which incorporatesthe crowding distance computation and the constraints handling, to design ideotypes for sustainable fruitproduction systems. The design of peach ideotypes that satisfy the requirement of high fruit quality and lowsensitivity to brown rot in a given environment was formulated as a multi-objective problem, and both NSGA-IIand MOPSO-CD are used to find the best combinations of genetic resources and cultural practices adapted to, andrespectful of specific environments. Statistically significant performance measures are employed to compare thetwo algorithms.
