CBSH2

Improved Heuristics for Multi-Agent Path Finding with Conflict-Based Search [1].

A more recent implementation with more CBS improvement techniques can be fonud here: https://github.com/Jiaoyang-Li/CBSH2-RTC

The main goal is to improve heuristics for Conflict-Based Search by reasoning about pairwise dependencies between agents. The code also contains the rectangle-symmetry reasoning technique RM from [2].

The code requires the external library BOOST (https://www.boost.org/). After you installed BOOST and downloaded the source code, go into the directory of the source code and compile the code with CMake:

cmake .
make

Then, you are able to run the code:

./CBSH2 -m instances/lak503d.map -a instances/lak503dmap-100agents-2.agents -o test.csv -t 60 -s 1 -h WDG -r 1

You can find details and explanations for all parameters with:

./CBSH2 --help
