We studied the problem of finding the maximum-density path in a tree. By spine decomposition and a linear-time algorithm for the maximum density segment problem, we developed an O(nlogn) time algorithm, which improves the previously best result of O(nlog^2n) by using centroid decomposition. We also show the time complexity is optimal in the algebraic computation tree model.
