Data deduplication has received a lot of attention from the research community. The research efforts have resulted in a state-of-the-art data deduplication pipeline, supported by software tools and

Effective and Efficient Heuristic Algorithms for Supporting Optimal Location of Hubs over Networks won of the mathematical model that we carved to fit the operational needs of .. Afterwards, we propose . able to solve the problem in a faster way with .. The heuristic algorithms proposed in our framework progressively reach a good approximation of the solution. Experimental results confirm the benefits of our approach.
