Fast query execution for retrieval models based on path-constrained random walks
Many recommendation and retrieval tasks can be represented as proximity queries on a labeled directed graph, with typed nodes representing documents, terms, and metadata, and labe...

Accelerated Proximity Queries for Haptic Rendering of Deformable Models
We present a fast proximity query algorithm for haptic display of complex deformable models using a layered representation. Assuming that each solid model can be represented as a ...

Proximity Queries between Convex Objects: an Interior Point Approach for Implicit Surfaces
— This paper presents an interior point approach to exact distance computation between convex objects represented as intersections of implicit surfaces. Exact distance computatio...
