Usage

This packaged version of Theta is equipped with the necessary SMT solvers, libraries and binary version of Theta. To use it, one has to simply execute theta-start.sh with the desired parameters. The first parameter must be the name of the input task (except when using --version). The script provides the --smt-home directory to Theta.
The tool is used with the following parameters on SV-Comp 2023:

--witness-only \
--portfolio COMPLEX \
--loglevel RESULT

For a more verbose output, change --witness-only to --output-results and --loglevel to MAINSTEP, SUBSTEP, INFO or DETAIL.
For more parameters, check out the documentation on CEGAR (might not be up to date on every parameter, but gives a detailed explanation on them) and the main class of the XCFA frontend.

v4.2.2

This release adds "no refinement progress detection" to the XSTS cli.
(Turning it off is possible with the --no-stuck-check flag)

v4.2.1

This release fixes a bug related to local variables in the XSTS formalism.

v4.2.0

This release adds basic function support to Theta, meaning it can now verify recursive programs. The previously used function inlining can be turned back on with the --inline ON flag.

v4.1.0

The new release contains a partial order reduction algorithm for multi-threaded programs. The algorithm has a formalism-independent core (PorLts), and an implementation for the XCFA interleavings algorithm (XcfaPorLts). POR can be enabled with the --algorithm INTERLEAVINGS_POR flag.
