Since, the algorithm is more computational intense, it is recommended to use all your idle computational power by setting Since, the algorithm is more computationally intense, it is recommended to use all your idle computational power by setting
the number of threads you want to use (try for example noThreads = #cores+1 first). the number of threads you want to use (try for example noThreads = #cores+1 first).

By using <code>.setProperty(...)</code> you can basically configure the algorithm the way you want.
This way, you can even change it back to the schrimpf-configuration.
The second major improvement is that we changed the way locations are defined. Instead of separately assigning location-id and coordinates, The second major improvement is that we changed the way locations are defined. Instead of separately assigning location-id and coordinates,
we encapsulated these attributes in an object called Location. It is not only clearer, but it we encapsulated these attributes in an object called Location. It is not only clearer, but it
allows you to assign a location index. Thus, you can save the transport times and distances allows you to assign a location index. Thus, you can save the transport times and distances
