一个能解中国古代算数定理（即孙子定理）的小程序

识别0~9阿拉伯数字，输入为yuv格式图片。Demo共分为两个程序，create_number和number_identification。create_number程序随机生成一个10位数，并建立YUV文件，生成的文件存放位置为../test_data/random_number.yuv。yuv为像素域的色彩空间，也就是图片解压后的结果，是常用的数字图像处理的色彩空间。number_identification程序对random_number.yuv文件里的数字进行识别，打印输出结果。

设计一个O(n*n)时间的算法，找出由n个数组成的序列的最长单调递增子序列--design an O (n2) time algorithm to identify by the number n of the longest sequence monotonically increasing sequences.

A program to demonstrate the optimization process of ant colony optimization for the traveling saleman problem (TSP). The cities are shown as red circles, the pheromone on the connections between them (fully connected graph) by gray lines. The darker the grey, the more pheromone is currently on the edge. During the optimization, the currently best found tour is drawn in red. To run the optimization, first create a random TSP, then create an ant colony, and finally run the optimization.
