— In this paper, we introduce a search engine, Dgoogle, designed for large scale P2P systems. Dgoogle is purely text-based, does not organize documents based on pre-defined keyw...
— Hyper-heuristics or “heuristics that coordinate heuristics” are fastly becoming popular for solving combinatorial optimisation problems. These methods do not search directl...
— In this work, we show that heuristic techniques (particularly Simulated Annealing) can be successfully applied in the search of good non-linear approximations of cryptographic ...
Search engines are playing a more and more important role in discovering information nowadays. Due to limitations of time-consuming, network bandwidth and hardwares, we cannot obt...
Screening is an important task to convert a continuoustone image into a binary image with pure black and white pixels. The main contribution of this paper is to show a new algorit...
