The Longest Path Problem is Polynomial on Cocomparability Graphscomplete on general graphs and, in fact, on every class of graphs that the Hamiltonian path problem is NP-complete. Polynomial solutions for the longest path problem have recently been proposed for weighted trees, ptolemaic graphs, bipartite permutation graphs, interval graphs, and some small classe

On Stable Matchings and Flowsthat there always exists a stable flow and generalize the lattice structure of stable marriages to stable flows. Our main tool is a straightforward reduction of the stable flow problem to stable allocations.

Solving Capacitated Dominating Set by Using Covering by Subsets and Maximum Matchingit has capacity to dominate. Cygan et al. showed in 2009 that this problem can be solved in . or in ..(1.89.) time using maximum matching algorithm. An alternative way to solve this problem is to use dynamic programming over subsets. By exploiting structural properties of instances that can not be s
