Example 3. 3 Sufficient conditions The prettiest condition that does guarantee Hamiltonian cycles in a graph comes from the 8. The algorithm to find strongly connected components involves running depth-first search on the original graph to find finishing times, then running DFS on the transpose graph considering vertices in order of decreasing finishing time. Ensuring the presence of a Hamiltonian cycle in a circuit guarantees the reliability and proper functioning of electronic devices. 1. Many Hamilton circuits in a complete graph are the same circuit with different starting points. Let i be the least integer for which x i is incident with one of the remaining edges. A Hamiltonian circuit is a path that starts at a certain point, travels along the edges, visits every point exactly once, and then returns to the Any Hamiltonian circuit can be converted to a Hamiltonian path by removing one of its edges. Just as circuits that visit each vertex in a graph exactly once are called Hamilton cycles (or Hamilton circuits), paths that visit each vertex on a graph exactly once are called Hamilton paths. # Print the first vertex again to complete the cycle # Example usage graph = [ [0, 1, 0, Real-world Applications # Circuit design in electronics; Route planning and logistics; 10.
