有N件物品和一个容量为V的背包。第i件物品的费用是c，价值是w。求解将哪些物品装入背包可使这些物品的费用总和不超过背包容量，且价值总和最大。(There are N items and a knapsack capacity of V' s. No. i is the cost of items c, the value of w. Solving items into the backpack which will enable the cost of these items does not exceed the sum of the capacity of backpack, and the sum of the maximum value.)

二阶粒子群，比pso更加精确更加灵敏地优化函数。在标准pso算法中，微粒的飞行速度仅仅是微粒当前位置的函数，而二阶粒子群算法中微粒飞行速度的变化与微粒位置的变化有关(Second swarm, more sensitive and more accurate than pso optimize function. Pso algorithm in the standard, the particle particle flight speed is only a function of the current position, the second particle swarm flying speed of particles in the particle changes related to changes in the position)

Rotational Actuator Torque-Speed Characteristics This model generates the torque-speed characteristics for five different motor types. To select the motor type, right-click on the Electric Motor block, select Block Choice and then the desired motor. All motors have been sized for roughly the same mechanical power rating.

基于OFDMA系统的多用户资源分配算法，论文配备MATLAB代码，入门的好教材。(— Orthogonal Frequency Division Multiple Access (OFDMA) basestations allow multiple users to transmit simultaneously on different subcarriers during the same symbol period. This paper considers basestation allocation of subcarriers and power to each user to maximize the sum of user data rates, subject to constraints on total power, bit error rate, and proportionality among user data rates. Previous allocation methods have been iterative nonlinear methods suitable for ofine optimization. In the special high subchannel SNR case, an iterative root-nding method has linear-time complexity in the number of users and N logN complexity in the number of subchannels. We propose a non-iterative method that is made possible by our relaxation of strict user rate proportionality constraints. Compared to the root-nding method, the proposed method waives the restriction of high subchannel SNR, has signicantly lower complexity, and in simulation, yields higher user data rates.)
