Since minimum sum-of-squares clustering (MSSC) is an NP hard combinatorial optimization problem, applying techniques from global optimization appears to be promising for reliably clustering numerical data. In this paper, concepts of combinatorial heuristic optimization are considered for approaching the MSSC: An iterated local search (ILS) approach is proposed which is capable of finding (near-...

<span>One of the main difficulties facing certified documents documentary archiving system is checking stamps system, but, that may be contains complex background and surrounded by unwanted data. Therefore, objective this paper to isolate remove noise stamp. Our proposed method comprises four phases, firstly, we apply k-means algorithm for clustering stamp image into a number clusters mer...
