Handling equality constraints in evolutionary optimization

Barkat Ullah, Abu S.S.M.; Sarker, Ruhul; Lokan, Chris - In: European Journal of Operational Research 221 (2012) 3, pp. 480-490

Over the last few decades several methods have been proposed for handling functional constraints while solving optimization problems using evolutionary algorithms (EAs). However, the presence of equality constraints makes the feasible space very small compared to the entire search space. As a...

Interactive multiobjective optimization approach to the input–output design of opening new branches

Park, K. Sam; Shin, Dong Eun - In: European Journal of Operational Research 220 (2012) 2, pp. 530-538

We demonstrate a real-world application of the interactive multiple objective optimization (MOO) approach to the simultaneous setting of input and output amounts for the opening of new branches. As illustrated by the case example, all the branches of a fast-food company employ multiple inputs to...
