Continuous knapsack problem:Let's talk about a story first. If you are a thief, one day you go to the landlord's house to steal things. There are 4 Jin Jinsha, 2 catty silver sand, 10 catty copper sand.But the bad luck is, your bag can only pack 8 pounds of things. So what are you going to steal?We'll break the problem down into equations and constraints here.Equation: GX + sy + CZ--->max #gsc分布代表金银铜Constraint: X+y+z = 8G>s>zMax (g) =4 Max (s) =4 Max

Orthogonal projection is provided by glortho in OpenGL and OpenGL ES 1.0. we can regard orthogonal projection as a special form of Perspective Projection: that is, the near and far cropping surfaces are identical except for the Z position, so the objects are always the same size and will not become smaller even in the distance.

Axis functions are rich in functionality and are commonly used in the following formats:
Axis equal: vertical and horizontal axes with equal length scale.
Axis Square: Produces a square coordinate system (the default is a rectangle).
Axis Auto: Use the default settings.

We all know that there are 2 ways to debug when developing Android apps,One is Android virtual device (dummy emulator) and the other is real machine debugging .Here is the real machine debugging some of the installation steps:1. Install mobile USB drive on PCIf the driver is not installed or the computer does not automatically install the driver, can not detect the device, even if you complete the following 2 steps will also have the following tips: USB device not foundThe device can be seen on

The characteristics of 3G technology determine the special characteristics of its network regulation and network optimization. The experience of the manufacturer's network regulation and network optimization will directly affect the constr
A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem.

With the development of China's routing industry, it has also promoted the wide application of multi-functional wireless routers. The following describes the performance characteristics of functional wireless routers. The rapid development of wireless networks over the past few years is obvious to all, although there is still a certain gap with foreign countries, but we are very optimistic about the domestic wireless network prospects, here do not talk about what 3G, WiMAX, TD-SCDMA, the most cl

Problem Description: After installing the Android development environment in Mac OS X, when the connection is set up, it is not possible to connect the device, supposedly, Mac OS X does not need to install the driver, and does not need the tool such as pea clip.Problem solving: The device's USB Vender ID needs to be added to the. Android/adb_usb.ini, the devices that cannot be connected, are usually made of domestic phones. The steps are as follows:1. Open terminal, enter: System_profiler spusbd
Blue chip stocksIt refers to a listed company with a large share capital and market value, but not all large-disk shares can be called blue-chip stocks. Therefore, it is difficult to set a definite standard for blue-chip stocks.
