Added support for derived predicates in goals. 
By accident, the support for derived predicates in goals was missing.
This commit adds this, in a very similar way to how normal predicates
are handled in the goal description.

ASP planning tools for PDDL

Overview

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

plasp translates planning problem instances to ASP facts. plasp 3 supports the input languages PDDL 3.1 (only basic features currently) and SAS (full support of SAS 3), which is used by Fast Downward.

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

Usage

Translating PDDL to ASP Facts

PDDL instances are translated to ASP facts as follows:

$ plasp domain.pddl problem.pddl

Alternatively, PDDL instances may first be translated to SAS, the output format of Fast Downward.

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

This creates a file called output.sas, which may now be translated by plasp.

$ plasp output.sas

Solving the Translated Instance

The translated instance can finally be solved incrementally with clingo and a meta encoding, for instance, sequential-incremental.lp:

$ plasp domain.pddl problem.pddl > instance.lp
$ clingo encodings/sequential-incremental.lp instance.lp

Command-Line Interface

$ plasp [options] file...

plasp automatically detects the language of the input program.

See command-line interface for more details.

Output Format

plasp provides a uniform output format for SAS and PDDL input problems.

See output format for more details.

If you want to write your own meta encoding for plasp’s output, this simple example encoding gets you started.

Building

plasp requires boost and is built via CMake and a C++ compiler.

See building for more details.
