abstract = "The $-calculus is the extension of the [pi]-calculus,
built around the central notion of cost and allowing
infinity in its operators. We propose the $-calculus as
a more complete model for problem solving to provide a
support to handle intractability and undecidability. It
goes beyond the Turing Machine model. We define the
semantics of the $-calculus using a novel optimization
method (the k[Omega]-optimization), which approximates
a nonexisting universal search algorithm and allows the
simulation of many other search methods. In particular,
the notion of total optimality has been used to provide
an automatic way to deal with intractability of problem
solving by optimizing together the quality of solutions
and search costs. The sufficient conditions needed for
completeness, optimality and total optimality of
problem solving search are defined. A very flexible
classification scheme of problem solving methods into
easy, hard and solvable in the limit classes has been
proposed. In particular, the third class deals with
non-recursive solutions of undecidable problems. The
approach is illustrated by solutions of some
intractable and undecidable problems. We also briefly
overview two possible implementations of the
$-calculus.",
