Pseudocode Yes Algorithm 1: Thompson Sampling
Open Source Code No The paper mentions the use of "Abs Con solver (https://www.cril.univ-artois. fr/ lecoutre/software.html)" but does not provide any link or statement indicating that the authors' own implementation code is open-source or publicly available.
Open Datasets Yes The benchmarks are from the CSP solver competition (http://www.cril.univ-artois. fr/CSC09).
Dataset Splits No The paper evaluates its methods on 363 problem instances from 15 problem series and discusses runtime ratios, but it does not specify explicit training, validation, or test dataset splits typical for machine learning experiments.
Hardware Specification Yes The experiments were run on a 3.40GHz Intel i7-4770 machine.
Software Dependencies No The paper states: "We use the Abs Con solver (https://www.cril.univ-artois. fr/ lecoutre/software.html)" but does not specify its version number or any other software dependencies with version numbers.
Experiment Setup Yes CPU time is limited to 1800 seconds per instance and memory to 8GB. ... We employ a full initialization of variable impact and activity at the root node of the search tree using the singleton arc consistency ... We use the same lexicographic value heuristic (lexico) for all cases.
