Reproducibility Variable Result LLM Response
Research Type Experimental We empirically demonstrate that our method achieves a compromise between loss of performance and computational gain. We compared OLUCT with OLTA on a discrete 1D track environment2 and a continuous Physical Travelling Salesman Problem3 (PTSP) [Perez et al., 2012b].

Dataset Splits No The paper describes simulation settings and generation of episodes for evaluation, but does not provide explicit training, validation, and test dataset splits in the traditional sense, as it applies to planning algorithms that generate data on-the-fly rather than using a fixed dataset.
Hardware Specification No No specific hardware details (such as GPU or CPU models, memory, or cloud instance types) used for running experiments are provided in the paper.
Software Dependencies No No specific software dependencies with version numbers (e.g., Python 3.8, PyTorch 1.9) are provided in the paper.
Experiment Setup Yes The simulation settings are: q {0.0, 0.05, , 0.5}; n = 20 (budget); πdefault = πoptimal; H = 10 (simulation horizon for πdefault); Cp = 0.7; γ = 0.9. The decision criteria parameters were tuned to: τSDM = 80; τSDV = 0.4; τSDSD = 1; τRDV = 0.9. (for 1D Track) and The simulation settings are: s0 = (1.1, 1.1, 0, 0.1); q {0.0, 0.05, , 0.5}; σnoise = 0.02; n = 300 (initial tree budget); πdefault = πgo straight that applies no orientation variation; H = 50 (simulation horizon for πdefault); Cp = 0.7; γ = 0.99. The different decision criteria parameters were tuned to: τSDV = 0.02; τSDSD = 1; τRDV = 0.1. (for PTSP)
