Researchers propose an LLM-aided A* algorithm that uses large language models to generate intermediate waypoints for finding shortest paths in non-geometric network graphs where traditional geometric heuristics don't apply. The approach reduces node expansion by ~50% while maintaining near-optimal path costs, demonstrating that combining LLMs with classical algorithms can enhance network optimization.
Researchers demonstrate that graph neural networks can learn to execute classical graph algorithms exactly through a two-step training process combining MLPs with NTK theory.

Researchers present an algorithmic framework for efficiently maintaining sheaf cohomology computations on dynamically evolving cellular complexes, reducing edit processing time from O(mn³) to O(1) per operation under bounded local geometry assumptions.

Researchers introduce COPF, a framework for monitoring and controlling fairness in online link recommendation systems on evolving graphs. The system addresses the challenge that recommendation algorithms are performative—they change user behavior and create feedback loops that make traditional fairness estimates unreliable after deployment.
Researchers propose a graph-based framework using Maximum Independent Set algorithms to efficiently benchmark large language models by selecting diverse, non-redundant prompt subsets. Testing across 66 LLMs and four major benchmarks demonstrates consistent rankings with 25-48% prompt reduction while maintaining reliability, offering significant computational savings for LLM evaluation.
Researchers introduce GraphDC, a divide-and-conquer multi-agent framework that enables Large Language Models to solve complex graph algorithms more effectively by decomposing large graphs into smaller subgraphs for specialized agent reasoning. The approach significantly improves LLM performance on graph algorithmic tasks, particularly on larger instances where traditional end-to-end reasoning fails.
Researchers present CM-Tabu, a composite-move Tabu search algorithm that solves spatial redistricting optimization problems more effectively by expanding the feasible solution space while maintaining district contiguity constraints. The method uses graph analysis to identify minimal unit movements or swaps that preserve connectivity, achieving superior solution quality and computational efficiency compared to traditional approaches.
Researchers developed Self-Healing Router, a fault-tolerant system for LLM agents that reduces control-plane LLM calls by 93% while maintaining correctness. The system uses graph-based routing with automatic recovery mechanisms, treating agent decisions as routing problems rather than reasoning tasks.
