Research Type Theoretical We show that the problem is fixed-parameter tractable when parameterized by the rank-width of the incidence graph of the given classification instance. Our algorithm proceeds by dynamic programming using an NLC decomposition obtained from a rank-width decomposition. The key to the algorithm is a succinct representation of partial solutions. This allows us to limit the space and time requirements for each dynamic programming step in terms of the parameter.

Pseudocode No The paper describes the algorithmic steps and dynamic programming approach in prose and through lemmas, but it does not include any formal pseudocode blocks or clearly labeled algorithm sections.
Open Source Code No The paper does not provide any statements about releasing source code or links to a code repository for the described methodology.
Open Datasets No This paper is theoretical and focuses on algorithm design and fixed-parameter tractability for decision trees. It defines classification instances abstractly but does not involve practical datasets, training, or evaluation on data, so no dataset access information is provided.
Dataset Splits No This is a theoretical paper and does not involve empirical experiments with datasets. Therefore, no training/test/validation dataset splits are specified for reproducibility.
Hardware Specification No This is a theoretical paper focusing on algorithms and complexity. It does not describe any empirical experiments, and therefore, no hardware specifications are mentioned for running experiments.
Software Dependencies No This is a theoretical paper focused on algorithm design and complexity. It does not describe any empirical experiments, and thus, no specific ancillary software dependencies with version numbers are mentioned.
Experiment Setup No This paper is theoretical, presenting an algorithm and its fixed-parameter tractability. It does not involve empirical experiments, and consequently, no experimental setup details like hyperparameters or training configurations are provided.
