Parallel Exploration of Directed Acyclic Graphs using the Actor Model


Rahul Prabhu, et al.


In this paper we describe a generic scheme for the parallel exploration of directed acyclic graphs starting from one or more `roots' of the graph. Our scheme is designed for graphs with the following properties, (i) discovering neighbors at any node requires a non-trivial amount of computation, it is not a simple lookup; (ii) once a node is processed, all its neighbors are discovered; (iii) each node can be discovered through multiple paths, but should only be processed once.

Computing maximum likelihood thresholds using graph rigidity


Daniel Irving Bernstein, et al.


The maximum likelihood threshold (MLT) of a graph G is the minimum number of samples to almost surely guarantee existence of the maximum likelihood estimate in the corresponding Gaussian graphical model. Recently a new characterization of the MLT in terms of rigidity-theoretic properties of G was proved \cite{Betal}. This characterization was then used to give new combinatorial lower bounds on the MLT of any graph.

A Slice-Traversal Algorithm for Very Large Mapped Volumetric Models

Computer-Aided Design

Jeremy Youngquist, et al.


When the full-scale storing and retrieving of volumetric models is cost prohibitive, intersection queries require intelligent access to pieces generated on demand. To conform to a given curved outer shape without clipping, such models are often the result of a non-linear free-form deformation applied to a geometrically simpler, canonical model. The additional challenge is then to relate the intersection query back to the pieces of the pre-image of the conforming curved model.
