Abstract: A tree was given in which each node is associated with a pair of numbers that represent the value and the weight of the node.The weight constrained maximum-density path algorithm is to find the maximum-density path in the tree,that is the ratio of the summation of the nodes’ values to the summation of the nodes’ weights is maximum.After studing the current algorithm,we found that the maximum density path algorithm has limitations.We gave the way of bypassing the limitations.Finally we designed and improved the algorithm.
