Straight-Line Grid Drawings of 3-Connected 1-Planar Graphse drawings. We show that every 3-connected 1-planar graph has a straight-line drawing on an integer grid of quadratic size, with the exception of a single edge on the outer face that has one bend. The drawing can be computed in linear time from any given 1-planar embedding of the graph.作者: Constitution 時(shí)間: 2025-3-24 18:14
