0-1 knapsack problem implementation in c++. One of the fundamental problems in Dynamic Programming.

本系统基于反馈控制思想，由交直流转换电路、DC-DC变换器、步进电路模块和显示模块4个模块电路构成开关稳压电源。交直流转换电路整流部分采用全波桥式整流电路形式，DC-DC变换器以TL494有主核心设计并加上简单滤波电路及RC放电回路所构成的回路控制器。它能把脉冲宽度变化的信号转换成与脉冲宽度成正比变化的直流信号，进而实现闭环单回路控制。由单片机控制 数字定位器X9241的电阻,进而控制输出电压。显示模块由LCD1602构成。 (Based on feedback control of the system of thought, from AC-DC converter circuit, DC-DC converters, stepper circuit module and display module 4 module circuit switching power supply. AC-DC converter circuit using full-wave rectifier part of the circuit form of bridge rectifier, DC-DC converter to TL494 have the main core of the design and add a simple RC filter circuit and discharge circuit posed by the loop controller. It can change the pulse width signals into changes with the pulse width is proportional to the DC signal, and thus realize the closed-loop single-loop control. By the single-chip microcomputer to control the number of locator X9241 resistance, thereby control the output voltage. LCD1602 constituted by the display module.)

可实现动态菜单的效果，不同的菜单效果下的显示(Can achieve the effect of dynamic menu, different menus are displayed under the effect of)

超级示波器，对ucgui的运用很有帮助，新手不要错过了，老手看看也是不错的(Super oscilloscope, is of great help to the use of ucgui, novice don t missed, veteran see also is pretty good)

说明：  复件 类似WindowsXP中菜单,有左边的竖条,有图形,有图形背景,工具条菜单,等(copy of a menu similar to Windows XP, the left side of the vertical lines, graphics, graphics background, Toolbar menu, etc.)

说明：  动态创建右键菜单，及遍历文件夹内的指定类型的文件，点击文件名读取文件内容(Dynamically create context menu, and traverse the folders within the specified file type, click the file name to read the contents of the file)

提供PSCAD的断路器模型、DC2DC模型，适合初学者。(Provide PSCAD circuit breaker the model, DC2DC model, suitable for beginners.)
