`plasp` 3 is in early development and not intended for productive use yet.
|
|
|
|
`plasp` 3 translates planning problem instances to ASP facts.
|
|
`plasp` 3 supports the input languages [PDDL](https://helios.hud.ac.uk/scommv/IPC-14/software.html) (only basic features currently) and the [SAS](http://www.fast-downward.org/TranslatorOutputFormat) (full support of the current version 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 instance.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 now be solved incrementally with `clingo` and a meta encoding, for instance, `pddl-meta-sequential-incremental.lp`:
|
|
|
|
```bash
|
|
$ plasp domain.pddl problem.pddl > instance.lp
|
|
$ clingo encodings/pddl-meta-sequential-incremental.lp instance.lp
|
|
```
|
|
|
|
## Building
|
|
|
|
`plasp` requires a C++14 compiler (preferrably GCC ≥ 6.1 or clang ≥ 3.8), the `boost` libraries (≥ 1.55), and CMake for building.
|
|
|
|
```bash
|
|
$ 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`.
|
|
|
|
### Running the Tests
|
|
|
|
`plasp` provides unit tests written using the [Google Test](https://github.com/google/googletest) framework.
|
|
Before building and running the tests, make sure you have fetched the Google Test git submodule:
|
|
|
|
```bash
|
|
$ git submodule init
|
|
$ git submodule update
|
|
```
|
|
|
|
Afterward, build and run the tests as follows:
|
|
|
|
```bash
|
|
$ make run-tests
|
|
```
