compact knapsack problemcryptographyIn the present study we consider two variants of SchnorrShevchenko method (SS) for solving hard knapsack problems, which are on average faster than the SS method. Furthermore, we study the compact knapsack problem i.e. the solution space is not {0, 1} as ...

We demonstrate that a thin direction need not always be a good direction to branch on for solving the problem efficiently. Further, the integer width, which is the number of B&B nodes created when branching on the direction, may also not be an accurate indicator of good branching directions....
In this paper, additive knapsack-type public-key cryptography is reconsidered. We propose a knapsack-type public-key cryptosystem by introducing an easy quadratic compact knapsack problem. The system uses the Chinese remainder theorem to disguise the easy knapsack sequence. The encryption function of ...
Within this context we consider the Coverage problem where the requirement is to establish all the connections defined by the edges of an undirected graph G=(V,E), where nodes V represent the devices. We prove the problem is NP-hard even for the basic case of q=2. Then, we investigate...
