Graph connectivity and Hamiltonian properties lie at the heart of both theoretical combinatorics and practical network design. Connectivity quantifies the robustness of a network by the minimum number ...

The modern information society is enabled by photonic fiber networks characterized by huge coverage and great complexity and ranging in size from transcontinental submarine telecommunication cables to ...

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 ...
