In this paper a variable neighborhood search approach as a method for solving combinatory optimization problems is presented. A variable neighborhood search based algorithm for solving the problem concerning the university course timetable design has been developed. This algorithm is used to solve the real problem regarding the university course timetable design. It is compared with other algor...

Modal logics for reasoning about the power of coalitions capture the notion of effectivity functions associated with game forms. The main goal of coalition logics is to provide formal tools for modeling the dynamics of a game frame whose states may correspond to different game forms. The two classes of effectivity functions studied are the families of playable and truly playable effectivity fun...

We introduce and study higher-order coalition logic, a multi modal monadic second-order logic with operators [{x}ψ]φ expressing that the coalition of all agents satisfying ψ(x) can achieve a state in which φ holds. We use neighborhood semantics to model extensive games of perfect information with simultaneous actions and we provide a framework reasoning about agents in the same way as it is rea...

Multi-center location of pharmaceutical logistics is the focus research, and dynamic uncertainty multi-center a difficult point research. In order to reduce risk cost multi-enterprise, multi-category, large-volume, high-efficiency, nationwide centralized medicine distribution, this study explores best solution for planning delivery logistics. paper, based on idea big data, comprehensive conside...

In this paper, for a complete residuated lattice L, we present the categorical properties of ?-neighborhood spaces and their relationships to neighborhood stratified L-neighborhood spaces. The main results are: (1) category is topological category; (2) can be embedded in as reflective subcategory, when L meet-continuous lattice, subcategory; (3) continuous (resp., spaces) simultaneously corefle...

The Cedar-Riverside neighborhood in Minneapolis, located adjacent to the University of Minnesota on the West Bank of the Mississippi River (Figure 1), has served as a settlement for new immigrants for more than two centuries, starting with the influx of families from Eastern European countries during the 1800s. More recently, significant numbers of immigrants from Africa, and to a lesser degree...

<abstract><p>The aim of this paper is to prove the existence periodic solutions symmetric Newtonian systems in any neighborhood an isolated orbit equilibria. Applying equivariant bifurcation techniques we obtain a generalization classical Lyapunov center theorem case potentials with orbits non-isolated critical points. Our tool version Conley index. To compare indices compute cohomo...
