Research Type Theoretical The aim of this work is to formally analyze the effects of these modifications to HTN semantics on the computational complexity and expressivity of HTN planning. To facilitate analysis, we unify goal and task planning into Goal-Task Network (GTN) planning. GTN models use HTN and HGN constructs, but have a solution-preserving mapping back to HTN planning. We then show theoretical results that provide new insights into both the expressivity as well as computational complexity of GTN planning under a number of different semantics.

Pseudocode No The paper describes formal constructions and iterative processes (e.g., Construction 4.1, Construction 4.8) in prose and mathematical notation, but it does not present them as structured pseudocode blocks or explicitly labeled algorithms.
Open Source Code No The paper does not provide any statement or link indicating that source code for the described methodology is publicly available.
Open Datasets No The paper is theoretical and does not conduct experiments with datasets. Therefore, it does not mention public dataset availability.
Dataset Splits No The paper is theoretical and does not conduct experiments with datasets, so it does not provide details on training/validation/test splits.
Hardware Specification No The paper is theoretical and does not describe any experimental setup or computations that would require specific hardware, thus no hardware specifications are mentioned.
Software Dependencies No The paper is theoretical and does not describe any software implementation or dependencies with specific version numbers.
Experiment Setup No The paper is theoretical and does not describe any experiments, therefore no experimental setup details like hyperparameters or training settings are provided.
