First game preliminary plan Before Game Development, you usually need to perform preliminary analysis and planning on your own game. Organize and analyze all foreseeable problems. Although simple game planning can be built in mind. But as a tutorial, let's proceed with the process. First, I decided what kind of game I was doing. I thought it would be a tank war for the red and white machines. Because you can find a full set of

, (2) Empty Jar, (3) pour water from one jar into another. When pouring water between two containers, it is necessary to wait until the inverted jar is emptied, or the poured jar is full. For example, if a has 5 galons of water, B has a capacity of 8 galons and 6 galons of water. After a is switched to B, 3 galons are left in. A problem is given by a triple (Ca, CB, n), where Ca and CB are the capacities of the jugs A and B, respectively, and N is the goal. A solution is a sequence of steps th

above sample, which can be expressed Return to the above statement "the model has been set, the parameter is unknown". What we know is that the unknown is θ, so the likelihood is defined: In practice, the logarithm is usually obtained on both sides. The formula is as follows: This is called the log likelihood, but the average log likelihood. What we usually call the maximum likelihood is the maximum logarithm mean likelihood, that is: For example, in a blog of someone else, if there is a ja
