We introduce the notion of a candidate for “multiple valued universal constructions” and define stable functors (which generalise functors with left adjoints) in terms of fac...
Two of the most commonly used models in computational learning theory are the distribution-free model in which examples are chosen from a fixed but arbitrary distribution, and the ...
We present a general theory for the use of negative premises in the rules of Transition System Specifications (TSSs). We formulate a criterion that should be satisfied by a TSS in ...
We define and study bisimulation for proving contextual equivalence in an aspect extension of the untyped lambda-calculus. To our knowledge, this is the first study of coinductive...
There have been several e orts to create and use real maps in computer applications that automatically nd good map routes. In general, online map representations do not include in...
