Reproducibility Variable Result LLM Response
Research Type Experimental In Section 5, we empirically evaluate how many items are needed to guarantee envy-free and Pareto-optimal allocations for a fixed collection of agents. We find that the approximate multiplier algorithm needs relatively large numbers of items to ensure envy-freeness; that the round robin algorithm violates Pareto-optimality in almost all instances; and that the Maximum Nash Welfare (MNW) algorithm achieves both axioms already for few items but that its running time limits its applicability.

Pseudocode Yes Algorithm 1: Equalizing Multipliers
Open Source Code No No statement or link providing access to the source code for the methodology described in this paper was found.
Open Datasets No The paper describes using a 'set of ten agents with utility distributions from a simple parametric family of (0.1, 1.9)-PDF-bounded distributions' in its empirical evaluation, implying simulated data rather than a publicly available dataset with a specific link or citation.
Dataset Splits No The paper does not provide specific training/validation/test dataset splits. The empirical section uses randomly generated utility distributions and instances for evaluation, not a fixed dataset that would require such splits.
Hardware Specification No The paper vaguely mentions 'on consumer hardware' for runtime, but does not provide specific hardware details such as GPU or CPU models, or memory specifications.
Software Dependencies No The paper mentions using the 'optimization library BARON' but does not specify its version number or any other software dependencies with version numbers.
Experiment Setup Yes For a requested accuracy of δ = 10 5, our algorithm runs in 30 seconds on consumer hardware, and we verify analytically that the resulting multipliers indeed lie within this tolerance, undisturbed by numerical inaccuracies in the computation.
