Given a directed graph G, G of two adjacent vertex vi to vj paths can use
polynomial vi, vj, and dij remember the edge has a weight, and dij may consist in
Ω = {0, 1} within the scope of the solution system of linear equations to determine.
The results can be used to solve the shortest path and critical path problems of
directed graphs, and the method can also be extended to undirected graphs to solve
Hamiltonian roads and circuits, euler roads and circuits and other problems.
