> 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](https://helios.hud.ac.uk/scommv/IPC-14/software.html) (only basic features currently) and [SAS](http://www.fast-downward.org/TranslatorOutputFormat) (full support of SAS 3), which is used by [Fast Downward](http://www.fast-downward.org/).
|
||
|
||
Please get in touch with [Patrick Lühne](https://www.luehne.de) if you have any suggestions.
|
||
|
||
## Usage
|
||
|
||
### Translating PDDL to ASP Facts
|
||
|
||
PDDL instances are translated to ASP facts as follows:
|
||
|
||
```bash
|
||
$ plasp domain.pddl problem.pddl
|
||
```
|
||
|
||
Alternatively, PDDL instances may first be translated to SAS, the output format of [Fast Downward](http://www.fast-downward.org/).
|
||
|
||
```bash
|
||
$ ./fast-downward.py --translate --build=release64 domain.pddl problem.pddl
|
||
```
|
||
|
||
This creates a file called `output.sas`, which may now be translated by `plasp`.
|
||
|
||
```bash
|
||
$ 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`](encodings/sequential-incremental.lp):
|
||
|
||
```bash
|
||
$ plasp domain.pddl problem.pddl > instance.lp
|
||
$ clingo encodings/sequential-incremental.lp instance.lp
|
||
```
|
||
|
||
## Command-Line Interface
|
||
|
||
```bash
|
||
$ plasp [options] file...
|
||
```
|
||
|
||
`plasp` automatically detects the language of the input program.
|
||
|
||
See [command-line interface](doc/command-line-interface.md) for more details.
|
||
|
||
## Output Format
|
||
|
||
`plasp` provides a uniform output format for SAS and PDDL input problems.
|
||
|
||
See [output format](doc/output-format.md) for more details.
|
||
|
||
If you want to write your own meta encoding for `plasp`’s output, this [simple example encoding](encodings/sequential-incremental.lp) gets you started.
|
||
|
||
## Building
|
||
|
||
`plasp` is built via CMake and a C++ compiler.
|
||
|
||
See [building](doc/building.md) for more details.
