Abstract

We present an algorithm for incremental non-dominated sorting, a procedure to use with steady-state multiobjective algorithms, with the complexity of O(N(log N)^M−2) for a single insertion, where N is the number of points and M is the number of objectives. This result generalizes the previously known O(N) algorithm designed for two objectives.

Our experimental performance study showed that our algorithm demonstrates a superior performance compared to the competitors, including various modifications of the divide-and-conquer non-dominated sorting algorithm (which significantly improve the performance on their own), and the state-of-the-art Efficient Non-domination Level Update algorithm. Only for M = 2 the specialized algorithm for two dimensions outperforms the new algorithm.
