A new technique breaks Dijkstra's 70-year-old record: it finds routes faster in huge networks, changing graph theory forever.

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 ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

This paper describes an exact algorithm for the fixed charge transportation problem based on a new integer programming formulation that involves two sets of variables representing flow patterns from ...

MINNEAPOLIS--(BUSINESS WIRE)--Edmentum, a global education leader and a pioneer in online teaching and learning solutions, has announced that it is the winner of three awards, including a top honor ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.
