Exposing Weaknesses of Large Reasoning Models through Graph Algorithm Problems

Qifan Zhang, Jianhao Ruan, Aochuan Chen +4

Large Reasoning Models (LRMs) have advanced rapidly; however, existing benchmarks in mathematics, code, and common-sense reasoning remain limited. They lack long-context evaluation…

Attacking and Securing Community Detection: A Game-Theoretic Framework

Yifan Niu, Aochuan Chen, Tingyang Xu +1

It has been demonstrated that adversarial graphs, i.e., graphs with imperceptible perturbations, can cause deep graph models to fail on classification tasks. In this work, we exten…
