说明：  基于时间窗的电动车调度，利用了遗传算法，启发式算法进行编程(Electric vehicle scheduling based on time window is programmed by using genetic algorithm and heuristic algorithm.)

说明：  设计一个哈夫曼编码器 要求对一段数据序列进行哈夫曼编码，使得平均码长最短，输出各元素编码和编码后的数据序列。 ① 组成序列的元素是[0-9]这10个数字，每个数字其对应的4位二进制数表示。比如5对应0101，9对应1001。 ② 输入数据序列的长度为256。 ③ 先输出每个元素的编码，然后输出数据序列对应的哈夫曼编码序列。(Designing a Huffman Encoder Huffman coding is required for a data sequence to minimize the average code length and output the coded and coded data sequence of each element. (1) The elements that make up the sequence are the 10 digits [0-9], and each digit is represented by its corresponding 4-bit binary number. For example, 5 corresponds to 0101, 9 corresponds to 1001. (2) The length of the input data sequence is 256. (3) First output the encoding of each element, and then output the Huffman encoding sequence corresponding to the data sequence.)

说明：  优化后的PSO-ELM算法，可对信号进行预测(The optimized pso-elm algorithm can predict the signal)

使用一个变量实现线性回归，以预测餐馆的利润。 使用梯度下降法，假设 h (x) 由线性模型给出 ，定义代价函数为 。线性回归的目标就是要最小化这个代价函数。(To get started with the exercise, you will need to download the starter code and unzip its contents to the directory where you wish to complete the exercise. If needed, use the cd command in Octave/MATLAB to change to this directory before starting this exercise.)
