Oriented cycles

Witryna4 paź 2024 · As a natural first step, we consider two basic structures: paths and cycles. We further restrict our attention to weighted oriented paths and cycles with the natural orientation of all edges pointing in the same direction. We call these graphs weighted naturally oriented paths and cycles. WitrynaYou would call it dfs (graph, node1, node2), this is a generator useful in a loop, e.g. for path in dfs (graph, node1, node2) - if you want a list of paths from node1 to node2 you can simply paths = list (dfs (graph, node1, node2). – AChampion Apr 19, 2024 at 1:57 I tried graph = {2: [4, 1], 3: [2], 1: [4, 3]} but it always come out KeyError: 4

Motivated by this conjecture, Kelly, Kühn, and Osthus initiated a study of degree conditions forcing the containment of a directed cycle of a given length. WitrynaWe prove that every tournament of order n˚68 contains every oriented Hamiltonian cycle except possibly the directed one when the tournament is reducible. 2000 Academic Press 1.

This gives an approximate solution to a problem of Thomassen [21]. In fact, we prove the stronger result that G is still Hamiltonian if δ ( G )+δ + ( G )+δ − ( G )≥3 G /2 + α G .
