Many optimisation problems in transportation, logistics or telecommunications can be formulated as search on a multi-graph. An example of problems include the vehicle routing problem, hazardous ...

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 ...

Paths and cycles are the two pivotal elements in a network. Here, we demonstrate that paths, particularly the shortest ones, are incomplete in information network. However, based on such paths, many ...
