Sparse Relaxations for Coalition Structure Generation

Published:Dec 25, 2025 12:56
1 min read
ArXiv

Analysis

This paper investigates efficient algorithms for the coalition structure generation (CSG) problem, a classic problem in game theory. It compares dynamic programming (DP), MILP branch-and-bound, and sparse relaxation methods. The key finding is that sparse relaxations can find near-optimal coalition structures in polynomial time under a specific random model, outperforming DP and MILP algorithms in terms of anytime performance. This is significant because it provides a computationally efficient approach to a complex problem.
Reference

“Sparse relaxations recover coalition structures whose welfare is arbitrarily close to optimal in polynomial time with high probability.”

    ID-PaS : Identity-Aware Predict-and-Search for General Mixed-Integer Linear Programs

    Published:Dec 11, 2025 01:58
    1 min read
    ArXiv

    Analysis

    This article introduces a new approach, ID-PaS, for solving Mixed-Integer Linear Programs (MILPs). The core idea is to incorporate identity awareness into a predict-and-search framework. This likely involves using machine learning to predict solutions or guide the search process, leveraging the specific characteristics of the problem instances. The use of 'identity-aware' suggests the method considers the unique features or structure of each MILP instance. The source being ArXiv indicates this is a research paper, likely detailing the methodology, experimental results, and comparisons to existing methods.

    ArXiv

    Analysis

    The article focuses on the integration of AI and Mixed Integer Linear Programming (MILP) for instance space analysis in air transportation. The use of graph-based methods for explainability is a key aspect. The research likely aims to improve decision-making and optimization in the air transportation domain by leveraging the strengths of both AI and MILP. The focus on explainability suggests an attempt to address the 'black box' problem often associated with AI.
