We present a class of polymodal logics for which the set of terms indexing the modal connectives can be hierarchized in two levels: the set of Boolean terms and the set of terms b...
This is a contribution for very low bit rate video coding in real-time and software only on computers of PC class. It is based on frame replenishment with block coding using mean-...
A programming exercise on recursion in which students create drawings of simple and bracketed Lindenmayer Systems provides a context for exploring additional computer science conc...
We introduce a linear algebraic model of computation, the Span Program, and prove several upper and lower bounds on it. These results yield the following applications in complexit...
The limitations of linear chromosomes and conventional recombination operators are reviewed. It is argued that there are at least three classes of problems for which such represen...
