چکیده

Аннотация For two scheduling problems (O3||Cmax and AL3||Cmax) tight bounds of the optima localization intervals are found in terms of lower bounds (C̃ and Ĉ, respectively) computable in linear time. The main part of the proof was made with an aid of computer. As a by-product, we obtain linear-time approximation algorithms for solving these problems with worst-case performance ratios 4/3 and 5/3, respectively.

Pre-scheduling and Scheduling of Task Graph on Homogeneous Multiprocessor Systems

Task graph scheduling is a multi-objective optimization and NP-hard problem. In this paper a new algorithm on homogeneous multiprocessors systems is proposed. Basically, scheduling algorithms are targeted to balance the two parameters of time and energy consumption. These two parameters are up to a certain limit in contrast with each other and improvement of one causes reduction in the othe...

On some fixed points properties and convergence theorems for a Banach operator in hyperbolic spaces

In this paper, we prove some fixed points properties and demiclosedness principle for a Banach operator in uniformly convex hyperbolic spaces. We further propose an iterative scheme for approximating a fixed point of a Banach operator and establish some strong and $Delta$-convergence theorems for such operator in the frame work of uniformly convex hyperbolic spaces. The results obtained in this...
