I.SMOAlgorithmPrinciple
The SMO algorithm is similar to some SVM improvement algorithms in the past. It breaks down the whole quadratic planning problem into many small problems that are easy to handle. What's different is that, only the SMO Algorithm breaks down the problem to the smallest possible scale: Each optimization only processes the optimization problem of two samples and uses the analytical method for processing. We will see that this distinctive method has brought a series of incom

-In section 4.pci Express, only PCI Express configuration access mechanisms can be used.

Three ways to set AutoLayout-NSLayoutConstraint code, nslayoutconstraint
AutoLayout is a new layout technology introduced by Apple to replace autoresizing from IOS 6. There are three ways to set AutoLayout. Let me explain it one by one.
Before talking about the three setting methods, let's briefly talk about what actions autolayout can set.
1. View Size (absolute view size ).
2. View position (The position of the view relative to the parent view or sibling view ).
3. View alignment (relative to
