HTab, a hybrid logic tableau prover

HTab is a tableau-based satisfiability checker. It currently handles the hybrid logic H(:,E) with role inclusions, and terminates on all inputs.

Compiling and using

To build HTab, you will need at least GHC 8.6, and either cabal-install or stack. Dependencies, including hylolib

A summary of the htab flags is available by running:

htab --help

Model building

HTab can output a model in the dot format for a satisfiable formula by using the -m option with -d:

htab -f input.frm -m model.m -d
dot model.m  -Tpdf  -omodel.pdf

This requires the graphviz package to get the dot executable.
