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 ...

SIAM Journal on Applied Mathematics, Vol. 34, No. 1 (Jan., 1978), pp. 176-197 (22 pages) We consider a graph-theoretic elimination process which models Gaussian elimination on sparse systems of linear ...

Away from finding a magical algorithm that can compare any graph, even in the worst-case scenario, the ISTA researchers sought to understand the philosophy of why certain algorithms seem to work ...
