Evaluating Interactive Reasoning in Large Language Models: A Hierarchical Benchmark with Executable Games

Mingyuan Fan, Weiguang Han, Daixin Wang +3

We introduce a multi-turn interactive framework for reasoning evaluation that treats reasoning as active evidence acquisition and belief updating. Wherein, LLMs receive only the ta…
