A team of computer scientists has come up with a dramatically faster algorithm for one of the oldest problems in computer science: maximum flow. The problem asks how much material can flow through a ...

Computer scientists at ETH Zurich have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum ...

The ‘flow accumulation’ algorithm in ArcGIS uses a recursive calculation to add values to grid cells based on a ‘flow direction’ raster, which is typically derived from a cost surface or ...

Algorithm promises to greatly streamline solutions to the 'max flow' problem. Research could boost the efficiency even of huge networks like the Internet. Finding the most efficient way to ...

Horn found that the literature on traffic flow instabilities had proposed a range of values for all those variables, and within those ranges, his algorithm works very efficiently. But in fact ...

In GIS analysis, flow-accumulation algorithms are usually used to model how water flows over satellite-derived maps that have grid cells representing elevation 3. Frachetti and colleagues adapted ...

Previous maximum flow algorithms made steady and incremental advances, but they still took longer to find the optimal flow than to process the network data. But the new research, presented on June ...
