When teaching a course in compiler design, it is conventional to introduce the iterative calculation of least fixed points quite late in the course, in the guise of iterative dat...
We present a simple, but efficient view collision detection method for the walk-through system. The basic idea is to check if the current view position intersects with the range d...
I present a general framework for observing and controlling a distributed computation and its applications to distributed debugging. Algorithms for observation are useful in distr...
We describe the Maple [23] implementation of multivariate factorization over general finite fields. Our first implementation is available in Maple V Release 3. We give selected det...
We present a framework for encoding planning problems in logic programs with negation as failure, having computational e ciency as our major consideration. In order to accomplish o...
