Parallel Exploration of Directed Acyclic Graphs using the Actor Model
arXivRahul Prabhu, et al.
2022-12-10
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
arXivDaniel Irving Bernstein, et al.
2022-10-20
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 DesignJeremy Youngquist, et al.
2021-12-01
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.
