An ǫ-NN graph is diﬀerent from a K-NNG in that undi-rected edges are established between all pairs of points with a similarity above ǫ. These methods are eﬃcient with a tight similarity threshold, when the ǫ-NN graphs constructed are usually very sparse and disconnected. Thus, eﬃcient K-NNG construction is still an open prob- The graphs \(K_5\) and \(K_{3,3}\) are two of the most important graphs within the subject of planarity in graph theory. Kuratowski’s theorem tells us that, if we can find a subgraph in any graph that is homeomorphic to \(K_5\) or \(K_{3,3}\), then the graph is not planar, meaning it’s not possible for the edges to be redrawn such that they are …The term '(K-N)/K' in the equation for logistic population growth represents the environmental resistance, where K is the carrying capacity and N is the number of individuals in a population over time. ...
