ShadowProver is a theorem prover (multi-modal logic with quantifiers).

Explicit setup instructions are for Debian/Ubuntu but generalize to most platforms. Clone the repository, be sure to use --recurse-submodules to ensure the snark theorem prover submodule is cloned.

git clone --recurse-submodules https://github.com/RAIRLab/ShadowProver.git

ShadowProver requires Java 8 and Maven.
WARNING: ShadowProver has been known to not work on newer versions of Java.

#Install Java 8, make sure you have the correct version on PATH
sudo apt install openjdk-8-jdk
#Install Maven
sudo apt install maven

Maven is used to build the prover to the /target directory.

mvn package

To run shaowprover ensure the /target directory has been built to, and the snark submodule has been cloned. From here you may run the provided script in the project root to run ShadowProver on a problem file. Problem files and examples can be found in the /problems/ directory, for basic examples see /problems/tutorial.

./run_shadowprover.sh [problem_file_path]

Additionally a docker based python interface exists on Naveen's branch, which can be found here.

ShadowProver is a novel multi-modal + extensional logic theorem prover that uses a technique called shadowing (the namesake of the prover) to achieve speed without sacrificing consistency in the system. For a detailed overview see the wiki.
