Almost-Uniform Sampling of Points on High-Dimensional Algebraic Varieties
We consider the problem of uniform sampling of points on an algebraic variety. Specifically, we develop a randomized algorithm that, given a small set of multivariate polynomials ...

Two Algebraic Process Semantics for Contextual Nets
We show that the so-called ‘Petri nets are monoids’ approach initiated by Meseguer and Montanari can be extended from ordinary place/transition Petri nets to contextual nets by...

An Algebraic Approach to Affine Registration of Point Sets
This paper proposes a new affine registration algorithm for matching two point sets in IR2 or IR3. The input point sets are represented as probability density functions, using e...

Initial Algebra Semantics for Cyclic Sharing Structures
Terms are a concise representation of tree structures. Since they can be naturally defined by an inductive type, they offer data structures in functional programming and mechanis...
