With the increasing demand for interactive services, it is important to investigate joint uplink/downlink resource allocation scheme in wireless networks, because the performance of the interactive service is determined by uplink and downlink jointly. In this paper, we propose a joint uplink/downlink resource allocation (RA) scheme in wireless orthogonal frequency division multiple access (OFDM...

In this paper we study the problem of approximately releasing the cut function of a graph while preserving differential privacy, and give new algorithms (and new analyses of existing algorithms) in both the interactive and non-interactive settings. Our algorithms in the interactive setting are achieved by revisiting the problem of releasing differentially private, approximate answers to a large...

This paper introduces a framework for the interactive solving of optimization problems and presents an interactive tabu search algorithm for the pick-up-and-delivery problem with time windows (PDPTW). The framework for the development of interactive algorithms is based on the idea of activating and deactivating constraints in the model of the problem under consideration. We start with an introd...

a vast number of organizational projects as well as complexity of decision making process can cause particular challenges for project management and its leadership. in order to use organization assets and opportunities efficiently, it is necessary that manager implement a comprehensive multidimensional project portfolio management system that considers economic, social and technical details of ...

This paper presents an interactive motion planning system to compute free collision motion in a numerical model. The system is based on interaction between a user and a motion planning algorithm. On one hand the user moves the object with an interactive device and on the other hand a motion planning algorithm searches a solution in the configuration space. The interaction aims at improving the ...

The multiobjective two person matrix game problem with fuzzy payoffs is considered in this paper. It is assumed that fuzzy payoffs are triangular fuzzy numbers. The problem is converted to several multiobjective matrix game problems with interval payoffs by using the $alpha$-cuts of fuzzy payoffs. By solving these problems some $alpha$-Pareto optimal strategies with some interval outcomes are o...
