**Pyperplan** is a lightweight STRIPS planner written in Python.

Please note that Pyperplan deliberately prefers clean code over fast
code. It is designed to be used as a teaching or prototyping tool. If
you use it for paper experiments, please state clearly that Pyperplan
does not offer state-of-the-art performance.

It was developed during the planning practical course at
Albert-Ludwigs-Universität Freiburg during the winter term 2010/2011 and
is published under the terms of the GNU General Public License 3
(GPLv3).

Pyperplan supports the following PDDL fragment: STRIPS without action
costs. This file only gives the basic information to get you up and
running. The full documentation can be found in the doc directory. You
can either read the text file documentation.txt directly or run "make"
in the doc directory to convert it to a PDF document.

# Requirements

Pyperplan is written in Python 3, so you need a recent version of Python
3 installed to run it. If Python 3 is not installed on your system, you
can download it from <http://python.org>. Alternatively, most current
Linux distributions include Python 3. For example,

> sudo apt install python3

will install Python 3 on an Ubuntu system.

# Usage

The planner is invoked through the file src/pyperplan.py and accepts two
arguments: a PDDL domain file and a PDDL problem file. Example:

> ./src/pyperplan.py benchmarks/tpp/domain.pddl
> benchmarks/tpp/task01.pddl

The domain file can be omitted, in which case the planner will attempt
to guess its name based on the problem file. If a plan is found, it is
stored alongside the problem file with a .soln extension.

By default, the planner performs a blind breadth-first search, which
does not scale very well. Heuristic search algorithms are available. For
example, to use greedy-best-first search with the FF heuristic, run

> ./src/pyperplan.py -H hff -s gbf DOMAIN PROBLEM

For a list of available search algorithms and heuristics, run

> ./src/pyperplan.py --help

For more information on using the planner and how to extend it to do
more fancy stuff, see doc/documentation.md.
