A bounded archive based for bi-objective problems based on distance and e-dominance to avoid cyclic behavior

One important issue in evolutionary multi-objective optimization (EMO) which still leaves room for improvement is the maintenance of the subset of the obtained candidate solutions that forms the approximation of the Pareto front (in short: selection or archiving). Existing archivers that are entirely based on the distances between the candidate solutions are known to reveal cyclic behavior and do hence not tap their full potential. On the other hand, there exist archivers based on ∊-dominance that guarantee monotonic behaviors as well as certain approximation qualities in the limit. For such methods, however, so far the magnitudes of the final archive size heavily depend on several design parameters and cannot be bounded a priori which is desired by many EMO researchers.
