Developing a polynomial-time algorithm for 3-level Constrained Level Planarity.
Abstract
The content discusses the development of a polynomial-time algorithm for 3-level Constrained Level Planarity (CLP). It outlines the assumptions made, such as properness of the graph and no isolated vertices. The algorithm successively adds new constraints to maintain planarity while deducing total orders for each level. Implicit constraints like transitivity and planarity are crucial in dictating relative vertex positions. The propagation of these constraints is illustrated through examples.
Stats
G1 consists of a single main component with enclosed components nested within it.
Components hook into each other based on specific conditions, forming a unique hook chain.
Implicit constraints ensure transitivity and planarity in the constrained level planar drawing.
