Webthis paper presents four algorithms: the Lenstra-Lenstra-Lovasz (LLL) algorithm, the Block Korkine-Zolotarev (BKZ) algorithm, a Metropolis algorithm, and a convex relaxation of SVP. The experimental results on various lattices show that the Metropolis algorithm works better than other algorithms with varying sizes of lattices. WebBKZ algorithm replaces the swap in LLL algorithm by a full enumeration in the local projected lattice to get shorter vector. This vector will be inserted into the basis at a preselected place, and we use an LLL algorithm to remove the linear dependency. The size of the local projected lattice is ﬁxed and the place to do

WebThe number t(G) of spanning trees of a connected graph is a well-studied invariant.. In specific graphs. In some cases, it is easy to calculate t(G) directly: . If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.
