shortest path methodsPascal implementationThe linear assignment problem (LAP) is useful as a relaxation for difficult combinatorial optimization problems (quadratic assignment, travelling salesman). Theoretical developments for the LAP can often be extended to problems as minimum cost flow and transportation...
We develop a shortest augmenting path algorithm for the linear assignment problem. It contains new initialization routines and a special implementation of Dijkstra's shortest path method. For both dense and sparse problems computational experiments show this algorithm to be uniformly faster than the best...
Over the years, various improved solutions to the maximum flow problem were discovered, notably the shortest augmenting path algorithm of Edmonds and Karp and independently Dinitz; the blocking flow algorithm of Dinitz; the push-relabel algorithm of Goldberg and Tarjan; and the binary blocking flow ...

Summary: The shortest augmenting path ({\\\sc {Sap}}) algorithm is one of the most classical approaches to the maximum matching and maximum flow problems, e.g., using it Edmonds and Karp in 1972 have shown the first strongly polynomial time algorithm for the maximum flow problem. Quite as...

A sequential version of our algorithm improves over previously known time bounds as well. Reachability fromssources can be computed usingÕ(M(nμ)+s(n+n2μ)) work, whereM(r)=o(r2.37) is the best known work bound forr×rmatrix multiplication. The algorithm is based on augmentingGwith ...

Existing shortest-path algorithms for open and public transport networks are adapted to the many-to-many case with numerous speed-up techniques and are used in conjunction with a machine-learning algorithm to optimise the transfer points and paths between the transfer zones of journey profiles. The...
