This paper (AoT) achieves similar performance to Tree of Thoughts (ToT) but using far less queries, which makes it very suitable for tasks that require lower latency or less traffic at a reduced cost.
I think the paper "Algorithm of Thoughts: Enhancing Exploration of Ideas in Large Language Models" (AoT) is big competitor with this paper. It shows that we can get similar results to Tree of Thoughts just by using a single query. AoT seems to be even surpassing ToT in some of the experiments.
