Webannealing. Deterministic annealing is a heuristic algorithm which comes from information theory. The principle is de-scribed in analogy to statistical physics. The simulated per-formance for vertex identication, with the CMS detector, is presented. The results are compared to those obtained with the CMS reference algorithm. INTRODUCTION WebIn this paper, we discuss the Deterministic Annealing (DA) algorithm developed in the data-compression literature [13], [14]. The DA algorithm enjoys the best of both the worlds. On one hand it is deterministic, i.e., it does not wander randomly on the energy surface. On the other hand, it is still an annealing method designed to aim at the global
