摘要:

我们实现了一个自动化的战术证明器TacticToe顶部的HOL4交互式定理证明器。TacticToe从人类证明中学习哪种数学技术适用于每种证明情况。这些知识,然后使用一个蒙特卡罗树搜索算法,探索有前途的战术级证明路径。在单个CPU上,时间限制为60秒,TacticToe证明了HOL4标准库中7164个定理的66.4%,而具有自动调度的E prover解决了34.5%。结合TacticToe和E prover的结果,成功率上升到69.0%。

英文摘要:

We implement a automated tactical prover TacticToe on top of the HOL4 interactive theorem prover. TacticToe learns from human proofs which mathematical technique is suitable in each proof situation. This knowledge is then used in a Monte Carlo tree search algorithm to explore promising tactic-level proof paths. On a single CPU, with a time limit of 60 seconds, TacticToe proves 66.4 percent of the 7164 theorems in HOL4's standard library, whereas E prover with auto-schedule solves 34.5 percent. The success rate rises to 69.0 percent by combining the results of TacticToe and E prover.
