Abstract. Geometric straight-line programs [5, 8] can be used to model geometric constructions and their implicit ambiguities. In this paper we discuss the complexity of deciding w...
In POPL 2002, Petrank and Rawitz showed a universal result-finding optimal data placement is not only NP-hard but also impossible to approximate within a constant factor if P = NP...
Within the EP-Cache project, the Performance Cockpit has been developed to provide a unified GUI for a series of performance tools. This is achieved through the establishment of a...
We consider the computational complexity of producing the best possible offspring in a crossover, given two solutions of the parents. The crossover operators are studied on the cla...
