I need implement the epsilon constraint method for solve multi objective optimization problems, but I don´t know how to choose each epsilon interval and neither when to terminate the algorithm, that is to say the stopping criteria.
Epsilon constraint is a modeling approach that reduce the number of objectives of a multi-objective problem by transforming them into constraints. Hence, with epsilon ctrt you will not solve the problem but you get a new (less complicated) model. This latter, has to be solved with a method that requires a stopping criterion. Rephrasing it: stopping criterion does not apply to the model but to the solving approach which is not specified in your question.
