WitrynaAn NP-complete problem with known pseudo-polynomial time algorithms is called weakly NP-complete . An NP-complete problem is called strongly NP-complete if it is proven that it cannot be solved by a pseudo-polynomial time algorithm unless P = NP. The strong/weak kinds of NP-hardness are defined analogously. Examples [ edit] WitrynaParalleled Genetic Algorithm for Solving the Knapsack Problem in the Cloud. Authors: Javid Taheri.
