Acacia-Bonsai

This is a modern implementation of universal co-Buchi reactive synthesis algorithms using antichain data structures. The theory and practice is described in:

https://arxiv.org/abs/2204.06079

Dependencies

This program depends on:

• Boost C++ Library
• A modern C++ compiler (C++20 is used)
• The Meson Build System
• The Spot Library: Spot is automagically compiled as a submodule; however, it takes quite a bit of time to do so, and each build configuration of Acacia-Bonsai will recompile Spot. We recommend that Spot be separately compiled and installed.
• The Z shell, for some scripts.

Some of the tests also depend on:

• Valgrind

Compiling, running, benchmarking

To compile and run, use Meson:

$ meson setup build
$ cd build
$ meson compile
$ src/acacia-bonsai --help
  [...]
$ src/acacia-bonsai -f '((G (F (req))) -> (G (F (grant))))' --ins req --outs grant
REALIZABLE

Note that this will compile a debug version of Acacia-Bonsai. A benchmarking script is available at the root:

$ ./self-benchmark.sh --help

In particular, it can be used to build an optimized version of Acacia-Bonsai:

$ ./self-benchmark.sh -c best -B
  [...]
$ cd build_best
$ src/acacia-bonsai --help
$ src/acacia-bonsai -f '((G (F (req))) -> (G (F (grant))))' --ins req --outs grant
REALIZABLE

The -c option selects a configuration and the -B option deactivates actual benchmarking, so that only compilation is done.

Compiling for StarExec

You will need some wrapping script (see starexec directory). Additionally, you will need to compile in an x86_64 machine with everything statically linked because StarExec runs on an old linux with old libraries. For instance:

1. Set up a meson build library with

CXXFLAGS="-march=sandybridge -O3 -DNDEBUG" meson setup $BUILD_DIR --buildtype=release --prefer-static --default-library=static

2. Print the compilation command with meson compile -vC $BUILD_DIR for acacia-bonsai and add -static to ensure everything is statically linked.
