pointers should have the ownership of the COM component. As follows:

, the above state can also be optimized: Notice that the position of the special block only changes when it is exchanged with the white block, so we only use record F[X][Y][FX] f[x][y][fx], which represents the coordinates of the special block and a bearing (up and down), which represents the position of the white block in the special block. Thus, in order to simulate a special block move, we also preproce
on gradient descent method
If the reader's guide number and gradient definitions are not well understood, read the previous article, "Number of square guides and gradients."
Prior to the machine learning, it was found that the gradient descent method was the most important one in machine learning. The gradient descent algorithm process is as follows:
1) Random initial value;
2) iterate until it converges. Indicates the negative gradient direction at the place, indicating the learning rate.

For example, when registering and displaying information from different companies, we can pass in the information displayed by our system, based on the ID (unique value, external status) of the application, and display it according to

Import shader to your engine
Thanks to DirectX and xNa, it is easy to load the FX file and set all required parameters (you have done this in the previous chapter when drawing 2D and 3D straight lines ). In the next chapter, you will use a more general class, which can accept many different shader and set all required parameters in a more optimized way, however, this chapter only uses simpleshader in the engine.

think about the following situation: we need to develop a general execution engine. You can execute any task that implements a specific interface. When a task is submitted to this engine, the code of the task needs to be loaded first. Assuming that different customers submit different tasks for this engine, coincidentally, all these tasks have the same class name and package name. The question is whether the engine can respond differently to the information submitted by different users. The sam
