Benchmark Problems

The ILTP library is divided into a first-order and a propositional part. All problems are represented in the standardized syntax of the TPTP library for classical logic. Both problem sets include some documentation, e.g. papers about the ILTP library, comparison tables, statistics files and a readme file. The tptp2X tool and some format files are included as well. They can be used for converting the problems into a syntax used by some of the existing intuitionistic ATP systems.

The following readme files give a brief introduction on how to use the ILTP library:

The performance results of some intuitionistic ATP systems on these benchmark problems can be found in the provers and results section. Previous releases of the ILTP library are made available in the archive section. Please contact us if you would like to submit new problems suitable for benchmarking intuitionistic ATP systems.


First-Order Part

The first-order part of the ILTP library contains 2550 problems including 70 propositional problems. 667 of these problems are known to be Theorems, 96 are Non-Theorems. The status of the remaining 1787 problems is Unsolved or Open. See the documentation for a detailed description.
