Reproducibility Variable Result LLM Response
Research Type Experimental We now present a series of simulation studies that provide evidence that MORRF produces a representative set of samples from the Pareto set. Results from MORRF are obtained for path-planning problems with two objectives and three objectives, and are compared to a modified version of the NSGA-II multi-objective path-planning algorithm [Ahmed and Deb, 2013] as well as a variant of MORRF that uses a weighted sum rather than the Tchebycheff approach.

Pseudocode Yes Algorithm 1 Multi-Objective Rapidly exploring Random Forest; Algorithm 2 EXTENDRef (G, xnew, xnearest, k); Algorithm 3 EXTENDSub (G, xnew, xnearest, m)
Open Source Code No The paper does not provide information about open-source code for the described methodology.
Open Datasets No The paper describes simulated environments ('obstacle-free world', 'environment with obstacles') for path planning, and defines abstract problem spaces (e.g., 'X Rd', 'Xobs'), but it does not explicitly use or refer to a named, publicly available dataset with concrete access information (e.g., URL, DOI, specific citation to an established benchmark).
Dataset Splits No The paper does not explicitly provide information on training, validation, or test dataset splits, as its simulations appear to be conducted on generated environments rather than using pre-defined dataset splits.
Hardware Specification No The paper does not provide specific hardware details (e.g., CPU/GPU models, memory) used for running its experiments.
Software Dependencies No The paper mentions algorithms like NSGA-II and MOEA-D, but it does not provide specific software names with version numbers or reproducible details for ancillary software dependencies used in its implementation or experiments.
Experiment Setup Yes Each method was run for 5000 iterations and restricted to 30 solutions. STEER(): Given two points x and y, returns a point z on the line segment from x to y that that is no greater than η from y. NEAR(G, x, η): Returns a set of all vertices within the closed ball of radius rn centered at x, in which rn = min{( γ n )1/d, η}.
