Replication data for: a benchmark generator for ensemble-based discrete optimization

This package contains the datasets, experimental results and reference sets of the paper A benchmark generator for scenario-based discrete optimization. The following files are included: File test_instances.zip: contains the test instances (TP1 to TP10) used in the experiments. For each test instance, three files are available: TP_k_F_m.txt, which contains the earnings of each decision variable for each scenario; TP_k_F_m_probabilities.txt, which contains the probability of occurrence for each scenario; and TP_k_F_m_weights.txt, which contains the generated weights for each decision variable. The value of k ranges from 1 to 10, and m ranges from 2 to 4. File experimental_results.zip: contains the experimental results. There is a subfolder for each test instance, and within each subfolder, there are 31 files for each algorithm, containing the non-dominated solutions obtained in each of the 31 independent repetitions. File reference_sets.zip: contains the reference sets, which are the best-known solutions for each test instance. Each file is structured as follows: each row contains an N-sized decision vector separated by semicolons, and the last values correspond to the objective function values. For example, if it is a bi-objective problem, consider the last two values; if it is a three-objective problem, consider the last three values, and so on. File source_code.zip: contains the source code for the experimental setup, including the code for the algorithms and the scripts used to generate the figures.
