An enhancing algorithm for node robustness based on graph theory is proposed, which focus on the situation of poor network robust caused by the weak ability of anti-vulnerable attacks of nodes. The ...

Graph theory isn’t enough.. The mathematical language for talking about connections, which usually depends on networks—vertices (dots) and edges (lines connecting them)—has been an ...

Introduce students to nodes and graph theory and their use in operations research. Show how Dijkstra’s Algorithm can be used to find the shortest or quickest route between nodes in a network.

They presented it in June at the ACM Symposium on Theory of Computing, where they detailed an exponentially better method for checking whether a graph is planar. “The new algorithm is a remarkable ...

If we view random node in the graph and select the subgraph with center in this node and arbitrary diameter then for this subgraph the rate of number of type I nodes and whole number of nodes tend to ...

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many ...
