Out of the string theory swampland: New models may resolve problem that conflicts with dark energy by Foundational Questions Institute, FQXi ...

The Floyd-Warshall algorithm is a fundamental solution in graph theory for finding the shortest paths between all pairs of vertices in a weighted graph. This project explores the theoretical ...

Five years after the corner where George Floyd was killed became the epicenter of a national protest movement, the future of the site is unsettled.

Hard in theory, easy in practice: Why graph isomorphism algorithms seem to be so effective by Andreas Rothe, Institute of Science and Technology Austria Editors' notes ...

University of Virginia School of Engineering and Applied Science professor Nikolaos Sidiropoulos has introduced a breakthrough in graph mining with the development of a new computational algorithm.

The Floyd-Warshall algorithm is based on a simple idea: for any two nodes u and v in a graph, the shortest path between them can either be a direct edge (u,v), or it can go through some ...

This is the power of graph theory. However, graph theory doesn’t stop at social networks. It finds applications in everything from brain signal processing to solving Sudoku and airline scheduling.
