What is the algorithm that is based JSPRIT

What is the algorithm that is based JSPRIT, specifically CostMatrix? .for example Solomon or Dijktra.
thanks for your answers :smile:

Hi,
algorithm: Please find more info here: https://github.com/graphhopper/jsprit/blob/master/docs/Meta-Heuristic.md

transport costs: By default, it is Euclidean distance. However, you can easily specify your own cost matrix.
