An algorithm taking as input an integer N that prints all the integers from 0 to N would run in time exponential in the number of bits of N. So when we say an algorithm is "polynomial" or "exponential", what we means depends on what unit we are using. Typically, the unit corresponds to the size of the ...

WebThe Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph. It is slower than Dijkstra's algorithm for the same problem, but more versatile, as it is capable of handling graphs in which some of the edge weights are negative numbers. The algorithm was first … Web, A greedy block Kaczmarz algorithm for solving large-scale linear systems, Appl. Math. Lett. 104 (2024).
