Exploiting equalities in polynomial programming
We propose a novel solution approach for polynomial programming problems with equality constraints. By means of a generic transformation, we show that solution schemes for the (ty...

A power penalty method for linear complementarity problems
In this paper we propose a power penalty approach to linear complementarity problems (LCP) in a finite dimensional space. This approach is based on approximating the LCP by a nonl...

A note on polling models with renewal arrivals and nonzero switch-over times
We consider polling systems with general service times and switch-over times, gated service at all queues and with general renewal arrival processes. We derive closed-form express...
