This repository contains the code for the abstract "Nmbr9 as a Constraint Programming Challenge" by Mikael Zayenz Lagerkvist. The abstract is submitted to the 25th International Conference on Principles and Practice of Constraint Programming 2019.
The code is located in the directory code/ and is a CMake C++ 17
project.
- The code is licensed under the MIT license.

Gecode 6.2.0 is required to be
installed on the system before building. The code has only been tested
on a Mac, it is likely that another way of discovering and linking
Gecode might be needed for other platforms, currently the CMake
find_library method is used for finding and setting up Gecode.
First, create a new build directory code/build. From within build, use
$ cmake ..
$ make
to build the application.
There will be an executable produced src/nmbr9-cli that uses the
Gecode script command line driver for running the model.
As an example, running the instance described in the paper is done using
$ nmbr9-cli -solutions 0 -play-type free -max-value 6 -copies 2 -deck-size 5 -grid-size 8 -max-layers 3
and running the full problem is done using
$ nmbr9-cli -solutions 0 -play-type free -max-value 9 -copies 2 -deck-size 20 -grid-size 20 -max-layers 7
