## Abstract We prove that, for a fixed bipartite circle graph __H__, all line graphs with sufficiently large rankโwidth (or cliqueโwidth) must have a pivotโminor isomorphic to __H__. To prove this, we introduce graphic deltaโmatroids. Graphic deltaโmatroids are minors of deltaโmatroids of line grap

We prove the conjecture made by \(\mathrm{O}\). V. Borodin in 1976 that the vertex set of any planar graph can be decomposed into two sets such that one of them induces a 3-degenerate graph and the other induces a 2-degenerate graph. that is, a forest. c. 1995 Academic Press. Inc.
It is shown that a planar can always be to planar graph fewer vertices. It is shown if a planar cubic graph is edge-3colorable then the reduction of the number of its vertices is possible without changing colors of its edges.
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
Some new properties of the distribution of elements and vertices with respect to the windows of a connected planar graph G are established. It is also shown that a window matrix of G has properties similar to the properties of an incidence matrix of a graph which is not necessarily planar. A method
