摘要: The Shortest Common Supersequence Problem (SCSP) is a well-known hard combinatorial optimization problem that formalizes many real world problems. This paper presents novel randomized search strategy, called probabilistic beam (PBS), based on the hybridization between and greedy constructive heuristics. PBS competitive (and sometimes better than) previous state-of-the-art algorithms for solving SCSP. describes provides an experimental analysis (including comparisons with approaches) demonstrate its usefulness.
