Graph labeling: The process of assigning identifiers, often numerical, to the elements of a graph (vertices or edges) under specific constraints to facilitate problem solving in various applications.

Abstractions blog A New Algorithm for Graph Crossings, Hiding in Plain Sight Two computer scientists found — in the unlikeliest of places — just the idea they needed to make a big leap in graph theory ...

Similarly, the corona graph of a cycle Cn with K1, denoted as Cn ⊙ K1 is a graph on 2 n vertices obtained by attaching n pendant edges to the cycle Cn. Each vertex of the cycle is connected to a new ...

The graph class is responsible for representing the graph,using adjacency lists,and includes basic methods: -addEdge: Create connection between two vertices with weight. -removeEdge: Remove connection ...

Graph Definitions A solid understanding of the basic definitions is essential for understanding graphs, their practical applications and the key differences that distinguish them from networks. Basic ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...
