The degree diameter problem
WebThe problem with a lower bound on diameter is NP-hard, while the problem with an upper bound on diameter is solvable in polynomial time. ... When we have no degree/diameter constraints, since spanning trees form a base family of a matroid, the exchange property of the matroid bases ensures that there always exists a reconfiguration sequence ... WebA (Δ , D)-graph is a graph with maximum degree Δ and diameter at most D. The order of a graph with degree Δ ( Δ > 2) of diameter D is bounded by the Moore bound. It is known …

WebThe degree/diameter problem is to determine the largest possible order of d-regular graphs with diameter D for given d and D 2. This is a fundamental problem in graph theory [1, 4, 11, 19]. As a regular graph often models a network topology, which the degree of each node is limited due to some physical constraints, WebLoz, Eyal; Širáň, Jozef (2008), "New record graphs in the degree-diameter problem" (PDF), Australasian Journal of Combinatorics, 41: 63–80; External links.
