Optimizing wireless networks represents a complex task, directly affecting quality, coverage, capacity and cost. In this paper, a new coverage presentation method based on geographic information system is proposed for coverage optimization in CDMA work. The proposed method represents a novel approach in that it focuses on distribution of successful access points around the base station (BS), that...
Unit commitment (UC) is a very important issue of generation scheduling in electric power systems. A hybrid method combining the adaptive Lagrangian relaxation (ALR) and Genetic Algorithm (GA) is presented in this paper. By using Lagrangian multipliers to relax system-wide demand and reserve constraints, the UC problem is decomposed and converted into a two-level optimization problem. The low-level...
This paper presents an unknown environment robot path planning algorithm. The robot working environments are expressed by grid model; Using digital potential field generated initial path population, and its optimization find the shortest path, and individual evaluation function were processed fitness function both feasible path and unfeasible path fitness function, and then by increasing the deleted...
