We associate a CNF-formula to every instance of the mean-payoff game problem in such a way that if the value of the game is non-negative the formula is satisfiable, and if the va...
This paper proposes a cryptographic mechanism for metering the duration and/or the number of instances of running a data process. This mechanism has the following property: knowing...
Previous studies on safety of program transformations with respect to performance considered two criteria: preserving performance within a constant factor and preserving complexit...
This paper deals with the concept of auto-calibration, i.e. methods to calibrate a camera on-line. In particular, we deal with minimal conditions on the intrinsic parameters neede...
Abstract. We propose a simple, general, randomized technique to reduce certain geometric optimization problems to their corresponding decision problems. These reductions increase t...
