In this paper, we consider the performance-optimized nonbinary low-density parity check code over general linear group, i.e., $\bar{\cal C}$. A new methodology for constructing the binary representation [generalized binary representation (GBR)] of $\bar{\cal C}$ is proposed, which can be optimized with regard to both degree distributions and girth. As to the decoding of the GBR, we develop a low-complexity...
This work formulates for the first time a multiple traveling salesman problem (MTSP) with ordinary and exclusive cities, denoted by MTSP for short. In the original MTSP, a city can be visited by any traveling salesman and is thus renamed as an ordinary one in MTSP. A new class of cities is introduced in MTSP, called exclusive ones. They are divided into groups, each of which can be exclusively visited...
According to requirements for grading and characteristics, mathematical model of linear vibrating screen with the pursuit of minimum power consumption per productive is established. By means of MATLAB optimization technology, the best design is acquired. The results show that power consumption per productive obtained from optimization is decreased significantly compared with empirical design.
Capacitated vehicle routing problem (CVRP) is an NP hard problem and it has important practical value. For large-scale problems, it is quite difficult to achieve an optimal solution with traditional optimization methods due to the high computational complexity. In this paper, it is analyzed that the insufficiency of the traditional particle swarm optimization (PSO) to the discrete and combination...
