The existence of fake tea from non-origin impacts on the credibility and sales of the origin Longjing tea seriously. In order to weaken this impact, we proposed a technology using ant colony clustering algorithm in discrimination the origin of Longjing tea. Then acquired and analyzed the characteristics of the origin tea comprehensively, the 16 parameters of the images and spectra from each sample...
Binary ant colony algorithm has good performance in the function optimization problem. However, the drawbacks that easy to fall into the local optimization still exist. Through the analysis of “best-so-far” pheromone update rule, we get the lower probability bound under this update rule. Then binary ant colony algorithm with Balanced search bias is proposed. Experiment results have shown that the...
A hybrid algorithm combining genetic with simplex is proposed to solve time-optimal coplanar orbit transfer in this paper. The trajectory optimization problem comes down to constraint parameter optimization, where the nonlinear two-point boundary value problem is avoided. The genetic algorithm (GA) is used to get global optimal parameters and the simplex algorithm is adopted to improve the ability...
Digital watermarking has been used for a long time in digital media, such as the information used in geographic information system (GIS) and digital vector maps, for both authentication and tracing. This work proposes a digital watermarking algorithm for vector map, which based on data configuration of vector map, combines with the theory of error correction in the field of digital communication....
After analyzing the curvature expression, the inflection points were given by the known planar cubic Bezier control polygon information. Based on that, we proposed an algorithm that can quickly and accurately obtain the shape characteristic points of curve. Experimental results show that the algorithm is rapid, accurate, and robust.
We propose a novel resource demand model and a BFS-based algorithm for multi-domain L1VPN. The proposed model and algorithm are implemented on AMSON testbed by combining PCE and service plane, and verified by experiment results.
