  • Method Details

    • approximate

      double approximate(int currentNode)
      Returns:
      minimal weight of the specified currentNode to the 'to' node

    • setTo

      void setTo(int to)

    • reverse

      WeightApproximator reverse()
      Makes a 'reverse' copy of itself to make it possible using the two objects independent e.g. on different threads. Do not copy state depending on the current approximate calls. 'reverse' means the WeightApproximator should handle approximate calls towards the 'from' instead towards the 'to'.

    • getSlack

      double getSlack()
