This paper considers an on-line scheduling problem occurred in a service system with two classes (normal and special) of customers and two types (dedicated and flexible) of serve...
A model of resource access control is presented in which the access control to resources can employ user interaction to obtain the necessary permissions. This model is inspired by...
We study the smallest possible number of points in a topological space having k open sets. Equivalently, this is the smallest possible number of elements in a poset having k order ...
The concept of intersection numbers of order r for t-designs is generalized to graphs and to block designs which are not necessarily t-designs. These intersection numbers satisfy ...
In this paper, the global optimization problem with an objective function that is multiextremal that satisfies the Lipschitz condition over a hypercube is considered. An algorithm...
