Reproducibility Variable Result LLM Response
Research Type Experimental Our experimental evaluation compares the landmark heuristics with the hybrid ˆhrmax hbd heuristic [Scala et al., 2016a], which is, to our knowledge, the only existing admissible heuristic for cost-optimal numeric planning. We apply the heuristics in a standard forward state space planner using A , so as to minimise any noise in the evaluation. The cost-partitioning problem is solved with CPLEX 12.63. Ties are broken preferring higher g-values. All heuristics are computed on a per-state basis.5 The evaluation is done over four numeric, non-temporal domains that have featured in the International Planning Competition6, the SAILING and FARMLAND domains from our earlier paper [Scala et al., 2016a], and the COUNTERS and GARDENING domains by Frances & Geffner [2015]. ... Table 1 shows a summary of the results.

Pseudocode No The paper does not contain any structured pseudocode or clearly labeled algorithm blocks.
Open Source Code Yes The implementation is part of the ENHSP planning system, open sourced at https://bitbucket.org/enricode/the-enhsp-planner.
Open Datasets Yes The evaluation is done over four numeric, non-temporal domains that have featured in the International Planning Competition6, the SAILING and FARMLAND domains from our earlier paper [Scala et al., 2016a], and the COUNTERS and GARDENING domains by Frances & Geffner [2015].
Dataset Splits No The paper describes evaluation on various planning domains and instances, but it does not specify training, validation, or test dataset splits in the conventional sense of machine learning.
