The Straight-Line RAC Drawing Problem Is NP-Hard
Recent cognitive experiments have shown that the negative impact of an edge crossing on the human understanding of a graph drawing, tends to be eliminated in the case where the crossing angles are greater than 70 degrees. This motivated the study of RAC drawings, in which every pair of crossing edges intersects at right angle. In this work, we demonstrate a class of graphs with unique RAC combi...
متن کاملThe Sorting Buffer Problem is NP-hard
We consider the offline sorting buffer problem. The input is a sequence of items of different types. All items must be processed one by one by a server. The server is equipped with a random-access buffer of limited capacity which can be used to rearrange items. The problem is to design a scheduling strategy that decides upon the order in which items from the buffer are sent to the server. Each ...
متن کاملStraight-Line Drawing of Quadrangulations
This article introduces a straight-line drawing algorithm for quadrangulations, in the family of the face-counting algorithms. It outputs in linear time a drawing on a regular W×H grid such that W+H = n − 1 −∆, where n is the number of vertices and ∆ is an explicit combinatorial parameter of the quadrangulation.
متن کاملAliased Register Allocation for Straight-Line Programs Is NP-Complete
Register allocation is NP-complete in general but can be solved in linear time for straight-line programs where each variable has at most one definition point if the bank of registers is homogeneous. In this paper we study registers which may alias: an aliased register can be used both independently or in combination with an adjacent register. Such registers are found in commonly-used architect...
