Features for the 0-1 knapsack problem based on inclusionwise maximal solutions

1 code implementation16 Nov 2022 Jorik Jooken, Pieter Leyman, Patrick De Causmaecker

We show that the proposed features contain important information related to the empirical hardness of a problem instance that was missing in earlier features from the literature by training machine learning models that can accurately predict the empirical hardness of a wide variety of 0-1 knapsack problem instances.

NICE: An Algorithm for Nearest Instance Counterfactual Explanations

3 code implementations15 Apr 2021 Dieter Brughmans, Pieter Leyman, David Martens

We propose four versions of NICE, one without optimization and, three which optimize the explanations for one of the following properties: sparsity, proximity or plausibility.

Exploring search space trees using an adapted version of Monte Carlo tree search for combinatorial optimization problems

2 code implementations22 Oct 2020 Jorik Jooken, Pieter Leyman, Tony Wauters, Patrick De Causmaecker

The algorithm is based on Monte Carlo tree search, a popular algorithm in game playing that is used to explore game trees and represents the state-of-the-art algorithm for a number of games.
