Reproducibility Variable Result LLM Response
Research Type Experimental To support this claim, we present a series of experimental examples in which abstraction refining outperforms progressive widening, given equal simulation budgets.

Pseudocode Yes Algorithm 1 Progressive Widening procedure SAMPLE(s, a) ... Algorithm 2 Abstraction Refining procedure SAMPLE(s, a)
Open Source Code Yes We included each of the codebases used for the experiments in the main body of the paper in the supplementary material and included descriptions of our experiments in the appendix.
Open Datasets No The paper describes using a 'continuous variant of blackjack', 'a variant of the trap problem', and 'five by five Go' with Open Spiel, but does not provide concrete access information (link, DOI, specific repository, or formal citation with authors/year for a public dataset) for any of these.
Dataset Splits No The paper does not provide specific dataset split information (exact percentages, sample counts, citations to predefined splits, or detailed splitting methodology) needed to reproduce the data partitioning.
Hardware Specification No We did not keep track of the total amount of compute used. We used an internal cluster.
Software Dependencies No The paper mentions 'Open Spiel' but does not provide specific version numbers for any software dependencies.
Experiment Setup Yes For k = 1, setting α to a small value... abstraction refining with ϵn = n 0.1. ... Abstraction refining with ϵn = 2n 0.1 is shown in brown... Abstraction refining with ϵn = 0.1n 0.1 is shown in brown...
