## Abstract Regarding an infinite planar graph __G__ as a discrete analogue of a noncompact simply connected Riemannian surface, we introduce the combinatorial curvature of __G__ corresponding to the sectional curvature of a manifold. We show this curvature has the property that its negative values
A greedy randomized adaptive search procedure (GRASP) is a metaheuristic for combinatorial optimization. In this paper, we describe a GRASP for the graph planarization problem, extending the heuristic of Goldschmidt and Takvorian [ Networks 24 (1994) 69-73]. We review the basic concepts of GRASP: co
