This paper presents a two-stage hybrid heuristic for vehicle routing problem with pickups and deliveries. The first stage uses a simple simulated annealing algorithm to decrease the number of routes, while the second stage is to decrease total travel cost. The performance of the proposed algorithm was tested on benchmark instances involving from 100 to 600 customers. It produced high quality results,...
This paper introduces the adaptive equalizer of least squares in UWB system. And it is important that this paper finds out a sort of new algorithm bases on UWB system. The new algorithm can solve the contradiction between convergent speeds to sensitivity of noise. Obviously, which is better than RLS algorithm. The simulation indicates that this improved feedback type equalizer has better capability.
