A Function-Equivalent Components Based Simplification Technique for PEPA Models
PEPA has recently been extended with functional rates [1][2]. These functions allow the specification of indirect interaction between components in such a way that the rate of an a...

Minimizing Symmetric Set Functions Faster
We describe a combinatorial algorithm which, given a monotone and consistent symmetric set function d on a finite set V in the sense of Rizzi [Riz00], constructs a non trivial set...

Job Sequencing with Exponential Functions of Processing Times
We study single machine scheduling problems, where processing times of the jobs are exponential functions of their start times. For increasing functions, we prove strong NP-hardnes...

Minimization of convex functionals over frame operators
Abstract. We present results about minimization of convex functionals defined over a finite set of vectors in a finite dimensional Hilbert space, that extend several known results ...

Exact cubature for a class of functions of maximum effective dimension
We consider high dimensional integration in a broad class of functions where all elements have maximum effective dimension. We show that there exists an exact cubature with only t...
