I propose a set of criteria which distinguish a grand challenge in science or engineering from the many other kinds of short-term or long-term research problems that engage the int...
We illustrate basic features of the Lixto wrapper generator such as the user and system interaction, the capacious visual interface, the marking and selecting procedures, and the ...
Refinement semantics is an alternative to least fixpoint semantics that is more useful for programming. From it we derive a variety of rules for w h i l e-loops, for-loops, and loo...
We generalize algebraic operational semantics from sequential languages to distributed, concurrent languages using Occam as an example. Elsewhere, we will discuss applications to ...
We discuss the use in machine learning of a general type of convex optimisation problem known as semi-definite programming (SDP) [1]. We intend to argue that SDP’s arise quite n...
