Reasoning under uncertainty is always based on a specified language
or for malism, including its particular syntax and semantics, but
also on its associated inference mechanism. In the present volume
of the handbook the last aspect, the algorithmic aspects of
uncertainty calculi are presented. Theory has suffi ciently
advanced to unfold some generally applicable fundamental structures
and methods. On the other hand, particular features of specific
formalisms and ap proaches to uncertainty of course still influence
strongly the computational meth ods to be used. Both general as
well as specific methods are included in this volume. Broadly
speaking, symbolic or logical approaches to uncertainty and nu
merical approaches are often distinguished. Although this
distinction is somewhat misleading, it is used as a means to
structure the present volume. This is even to some degree reflected
in the two first chapters, which treat fundamental, general methods
of computation in systems designed to represent uncertainty. It has
been noted early by Shenoy and Shafer, that computations in
different domains have an underlying common structure. Essentially
pieces of knowledge or information are to be combined together and
then focused on some particular question or domain. This can be
captured in an algebraic structure called valuation algebra which
is described in the first chapter. Here the basic operations of
combination and focus ing (marginalization) of knowledge and
information is modeled abstractly subject to simple axioms."
