Parameterized Complexity of Fair Orientations in Graphs

Published:Dec 31, 2025 18:30

ArXiv

Analysis

This paper investigates the computational complexity of finding fair orientations in graphs, a problem relevant to fair division scenarios. It focuses on EF (envy-free) orientations, which have been less studied than EFX orientations. The paper's significance lies in its parameterized complexity analysis, identifying tractable cases, hardness results, and parameterizations for both simple graphs and multigraphs. It also provides insights into the relationship between EF and EFX orientations, answering an open question and improving upon existing work. The study of charity in the orientation setting further extends the paper's contribution.

Analysis

This paper introduces a novel random gradient-free optimization method tailored for infinite-dimensional Hilbert spaces, addressing functional optimization challenges. The approach circumvents the computational difficulties associated with infinite-dimensional gradients by relying on directional derivatives and a pre-basis for the Hilbert space. This is a significant improvement over traditional methods that rely on finite-dimensional gradient descent over function parameterizations. The method's applicability is demonstrated through solving partial differential equations using a physics-informed neural network (PINN) approach, showcasing its potential for provable convergence. The reliance on easily obtainable pre-bases and directional derivatives makes this method more tractable than approaches requiring orthonormal bases or reproducing kernels. This research offers a promising avenue for optimization in complex functional spaces.

“To overcome this limitation, our framework requires only the computation of directional derivatives and a pre-basis for the Hilbert space domain.”
