Parallel SAH k-D tree construction
The k-D tree is a well-studied acceleration data structure for ray tracing. It is used to organize primitives in a scene to allow efficient execution of intersection operations be...

Exact and Parameterized Algorithms for Max Internal Spanning Tree
We consider the NP-hard problem of finding a spanning tree with a maximum number of internal vertices. This problem is a generalization of the famous Hamiltonian Path problem. Our...

Nearly Tight Low Stretch Spanning Trees
We prove that any graph G with n points has a distribution T over spanning trees such that for any edge (u, v) the expected stretch ET ∼T [dT (u, v)/dG(u, v)] is bounded by ˜O(...

Self-Stabilizing Anonymous Leader Election in a Tree
We propose a new self-stabilizing anonymous leader election algorithm in a tree graph. We show the correctness of the protocol and show that the protocol terminates in O(n4 ) time...

Minimal Delay Interconnect Design Using Alphabetic Trees
Abstract - We propose a new algorithm for the performancedriven interconnect design problem, based on alphabetic trees. The interconnect topology is determined in a global manner a...
