Programs of a software product line can be synthesized by composing features which implement a unit of program functionality. In most product lines, only some combination of featu...
Stretch-A-Sketch is a pen-based drawing program that combines recognition of hand-drawn glyphs with constraint based maintenance of spatial relations. The recognition program iden...
In this paper we develop a variable neighborhood search (VNS) heuristic for solving mixed-integer programs (MIPs). It uses CPLEX, the general-purpose MIP solver, as a black-box. N...
Abstract. We illustrate the potential of conditional hedge transformations in Web-related applications on the example of PρLog: an extension of logic programming with advanced rul...
We introduce regular graph constraints and explore their decidability properties. The motivation for regular graph constraints is 1) type checking of changing types of objects in ...
