contexts such as construction of abstractions, speed may be favored over completeness, so that undecidable theories (e.g., nonlinear integer arithmetic) and those whose decision pr...
The main question addressed in the present work is how to find effectively a recursive function separating two sets drawn arbitrarily from a given collection of disjoint sets. I...
We present a new language feature, specified as an extension to Java. The feature is a form of dispatch which includes and subsumes multimethods (see for example [3]), but which ...
We give the first polynomial-time approximation scheme (PTAS) for the Steiner forest problem on planar graphs and, more generally, on graphs of bounded genus. As a first step, w...
Niklaus Wirth has received much deserved fame for the creation of Pascal, but in many ways, he subsequently became a victim of Pascal's success. In an age of rising specializ...
