行商问题是一个经典的NP完全问题,多人旅行商问题的求解则更具挑战性。以往对求解多人旅行商问题的研究局限于以所有成员路径总和最小为优化标准(Salesmen problem is a classical NP complete problem, many people are solving the traveling salesman problem more challenging. Solving the traveling salesman problem of many previous studies limited to minimize the sum of all the members of the paths to optimize the standard)

MATLAB图像处理源文件，每章节的对应matlab源代码已整理好，可对应ppt和视频配套学习(MATLAB image processing source files, each chapter corresponds matlab source code has been collated.)

利用均衡不完全区组设计(Balance Imcomplete Block Designs，BIBD)的半结构化低密度奇偶校验(Low Density Parity Check，LDPC)码设计方法。可以生成仿真结果曲线(The use of a balanced incomplete block design (Balance Imcomplete Block Designs, BIBD) semi-structured Low Density Parity Check Codes design methods. The simulation results can be generated curve.)
