Central to this domain is the pursuit of determining the minimum number of vertices required so that any colouring of a complete graph inevitably yields either a well-organised (monochromatic ...

Our lives are nodes in that grand web of interactions.” “Dots and Lines” is about modern network science. “At their most ...

Abstract: In this paper, we describe an Information retrieval Model based on graph comparison. It is inspired from previous work such as KleinbergpsilaHits and Blondel et al.psilas model. Unlike ...

Abstract: The problem of enumerating all the s-t minimal cutsets separating two vertices s and t specified in a class of undirected planar graphs, called D-S (delta-star) reducible graphs, is ...

If G is a finite group, we define its prime graph Γ(G) as follows. The vertices of Γ(G) are the primes dividing the order of G and two distinct vertices p, q are joined by an edge, denoted by p~q, if ...

Save guides, add subjects and pick up where you left off with your BBC account. A time graph is a line graph which shows you data that has been collected over a period of time. There is a title ...

They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they have. A three-dimensional (3D) shape is a solid ...

Note: Goods from Canada and Mexico that fall under the U.S.M.C.A. trade pact — the agreement that replaced NAFTA — are not subject to tariffs that took effect in March targeting those ...
