PILS: Exploring high-order neighborhoods by pattern mining and injection
作者:
Highlights:
• We introduce PILS: a new local search paradigm based on pattern mining and injection.
• Our method iteratively inserts a frequent pattern into the solution and completes it.
• This permits to detect high-order moves that would otherwise not be found.
• We apply it to the vehicle routing problem and propose an efficient completion algorithm.
• Our experiments demonstrate the large contribution of PILS to the search performance.
