I/O efficient path traversal in well-shaped tetrahedral meshes
We present a data structure which represents a wellshaped convex tetrahedral mesh, M, in linear space such that path traversals visiting a sequence of K tetrahedra require O (K/ l...

External Sampling
We initiate the study of sublinear-time algorithms in the external memory model [14]. In this model, the data is stored in blocks of a certain size B, and the algorithm is charged...
