Jesper Andreasson,Thomas Johanssoney are the Iterative Function Systems developed by Barnsley, the probabilistic finite generators, and probabilistic mutually recursive systems that generalize both former methods. We briefly introduce the formal notion of an image both as a compact set (of black points) and as a measure on Borel set

Jesper Andreasson,Thomas Johanssonthat has at least as many processors as M and, for any k>0, let Q(M/2.) be "M‘s 1/2.-size hypercube", which has 1/2. as many processors as M‘s optimum hypercube. The ratio MI/Q(M/2.) is called . 1/2.- .. We show that (a) for every 2-D mesh M, if M‘s 1/2-density≤1.828, then M can be embedded into its

We discuss then what we see as the seven most difficult topics in background knowledge acquisition, namely the detection of implicit implications, first order logic knowledge representation

Corresponding intractability results are mentioned as well. The evidence is presented why discrete neural networks (inclusively Boltzmann machines) are not to

We then consider and compare two possible ways of counting two-way reading on a regular language, and thus, of defining the behaviour of two-way automata. For e

We introduce and study derivation proofs to describe the sequences of rules used to reduce a term t in a term t‘ for a given ground rewrite system S and sketch how compute a derivation proof in

Several natural problems are shown to be complete for ⊕. under ..-reductions. A consequence is that ⊕. is the ..-analogon of Cook‘s class ., the class of problems ..-reducible

Come limitare i rischi da fitoterapici, a theorem. It may happen that F is . or, for some reason, that we fail to prove F. Several theorem proving methods provide different kinds of the so-called "failure formulae". The failure formulae explain why the proof of F failed..This paper illustrates the kind of failure formulae generated by th
