Method Summary

WeightApproximator	reverse() Makes a 'reverse' copy of itself to make it possible using the two objects independent e.g.
void	setTo(int to)

Method Detail

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()
