This paper presents the design and the features of a Web-based micro-world -the SORTING micro-world constructed for the learning of sorting algorithms by secondary level education students. The design of this microworld has been based on modern constructivist and social theories of learning. SORTING is an interactive environment that can support learners: a) to express their own sorting procedu...

this paper considers the job scheduling problem in virtual manufacturing cells (vmcs) with the goal of minimizing two objectives namely, makespan and total travelling distance. to solve this problem two algorithms are proposed: traditional non-dominated sorting genetic algorithm (nsga-ii) and knowledge-based non-dominated sorting genetic algorithm (kbnsga-ii). the difference between these algor...
