plasp—Translate PDDL to ASP

plasp 3 is in early development and not intended for productive use yet.

As of now, plasp 3 experimentally supports the full SAS Format (as of version 3) used by Fast Downward.

Please get in touch with Patrick Lühne if you have any suggestions.

Usage

To translate an SAS file into ASP facts, call:

$ plasp file.sas

For instance, a PDDL instance can be solved as follows. First, use Fast Downward to translate the files from PDDL to SAS:

$ ./fast-downward.py --translate --build=release64 domain.pddl instance.pddl

This creates the file output.sas. The translated SAS instance can now be solved incrementally with clingo and the meta encoding meta-sequential-incremental.lp:

$ plasp output.sas > instance.lp
$ clingo encodings/meta-sequential-incremental.lp instance.lp

Building

plasp requires a C++14 compiler (preferrably GCC ≥ 6.1), the boost libraries (≥ 1.55), and CMake for building.

$ git clone https://github.com/potassco/plasp.git
$ cd plasp
$ mkdir -p build/release
$ cd build/release
$ cmake ../.. -DCMAKE_BUILD_TYPE=Release
$ make

The built plasp binary is then located at plasp/build/release/bin/plasp.
