Thin Tree Verification is coNP-Complete

Published:Dec 31, 2025 18:38
1 min read
ArXiv

Analysis

This paper addresses the computational complexity of verifying the 'thinness' of a spanning tree in a graph. The Thin Tree Conjecture is a significant open problem in graph theory, and the ability to efficiently construct thin trees has implications for approximation algorithms for problems like the asymmetric traveling salesman problem (ATSP). The paper's key contribution is proving that verifying the thinness of a tree is coNP-hard, meaning it's likely computationally difficult to determine if a given tree meets the thinness criteria. This result has implications for the development of algorithms related to the Thin Tree Conjecture and related optimization problems.

CP Model and BRKGA for Single-Machine Coupled Task Scheduling

Published:Dec 29, 2025 02:27
1 min read
ArXiv

Analysis

This paper addresses a strongly NP-hard scheduling problem, proposing both a Constraint Programming (CP) model and a Biased Random-Key Genetic Algorithm (BRKGA) to minimize makespan. The significance lies in the combination of these approaches, leveraging the strengths of both CP for exact solutions (given sufficient time) and BRKGA for efficient exploration of the solution space, especially for larger instances. The paper also highlights the importance of specific components within the BRKGA, such as shake and local search, for improved performance.
Reference

“The BRKGA can efficiently explore the problem solution space, providing high-quality approximate solutions within low computational times.”
