SPRINGROLL HAS BEEN MOVED TO GITLAB. FOLLOW THIS LINK
This repository contains Springroll, an SMT based planner implementing ideas from
Numeric Planning with Disjunctive Global Constraints via SMT
Scala, E., Ramirez, M., Haslum, P. and Thiebaux, S., ICAPS 2016
Installing JAVA 1.8 in Ubuntu versions earlier than 16.04 requires to acquire the packages directly from Oracle as follows
sudo add-apt-repository ppa:webupd8team/java -y sudo apt-get update sudo apt-get install oracle-java8-installer sudo apt-get install oracle-java8-set-default
You will need to install Z3 from its sources by following the how-to guide provided by their authors. This means you will need to have GCC, make and Python installed on your system. As of August 2016, the provided instructions work entirely out of the box on Ubuntu systems. Compilation can take as much as half an hour on laptops CPUs with modest clock speeds.
The planner reads a slightly extended version of PDDL 2.1 (Fox, M. and Long, D., 2003. PDDL2. 1: An Extension to PDDL for Expressing Temporal Planning Domains. J. Artif. Intell. Res.(JAIR), 20, pp.61-124. Vancouver) and can be run by using:
./springroll -o <domain_file> -f <problem_file> -s <option> <option> is an integer number from 0 to 3 0: 1-step semantics, no rolling-up 1: 1-step semantics, rolling-up 2: foreach-step semantics, no rolling-up 3: foreach-step semantics, rolling-up
In case you need to compile the planner simply type
ant from the root directory. Note however that the low level encoding depends on a library called PPMaJal, which is provided in the
lib directory but still not open sourced. Apart from lower level translation, this library handles all the PDDL parsing and something else. We plan to open source it ASAP.
For more information, send me an email (firstname.lastname@example.org) or have a look at the aforementioned paper.
The version is experimental so there could be bugs. Please let me know if you find something which is not working.
The version comes with a motion planning problem in the mot_example folder. Other benchmarks can be found here
