Convex graph

A convex function has a second derivative that is not negative over the whole range of values. Some graphs such as the complete bipartite graph have convex drawings but not strictly.

A bipartite graph U V E is said to be convex over.

. A convex function is a real-valued function defined on an interval with the property that its epigraph the set of points on or above the graph of the function is a convex set. Introduction A graph G is defined by a set VG of vertices a set EG of. Choose a suitable but the same scale to denote v along the Y-axis and u along X-axis.

An ordering of X in a bipartite graph B XYE has the adjacency property if for every vertex y in Y N y consists of vertices that are. Concave up also called convex or concave down are descriptions for a graph or part of a graph. In metric graph theory a convex subgraph of an undirected graph G is a subgraph that includes every shortest path in G between two of its vertices.

In mathematics a convex graph may be. A convex bipartite graph. In the mathematical field of graph theory a convex bipartite graph is a bipartite graph with specific properties.
