launched in PHP V4.2.0 for experimental purposes. When you go to V4.3.0, you are fully supported and enabled by default. The PHP CLI SAPI allows you to develop PHP-supported shell scripts, even desktop based scripts. In fact, you can use PHP to create tools that you can run directly from the command line. In this way, PHP developers can be as efficient as Perl, AWK, Ruby, or shell programmers. This article explores the tools built into PHP to help you understand the underlying shell environmen

number . sentence B: This boots number is not small, it is more suitable How to calculate the similarity of the above two sentences. The basic idea is that if the two words are more similar in terms, their content should be more similar. Therefore, we can start with the word frequency and calculate their similarity. The first step, participle . sentence A: this/boots/number/Big one. That's/number/suitable

to each other. But from the score on the x doesn't seem to like 2 this content, and y is preferred, the cosine similarity to the value of the sensitivity of the results of the error, the need to correct this irrationality there is the adjustment of the cosine similarity, that is, all the dimensions of the value minus a mean, such as X and Y score mean is 3, then adjusted to (-2, -1), and then the cosine similarity calculation, get 0.8, the similarity is negative and the difference is not small,

probability: 1. Boots 20% 2. Cloak 25% 3. Accessories 10% 4. Two-handed Sword 5% 5. Coin bag 40% The question now is how to drop an item to the player based on probability. I. GENERAL algorithm : Generate a list, divided into several intervals, such as the length of the list 100,1-20 is the range of boots, 21-45 is the cloak of the interval, and then randomly from 100 to take out a number, to

exponential form in memory, as shown in Figure 2.3.Figure 2.3 The number portion must be less than 1, and the first number after the decimal point must be a non-0 number, for example, not 0.0314159. So 314.159 and 314.159e0, 31.4159e1, 3.14159e2, 0.314159e3 are represented in memory as 0.314159x103. The storage unit is divided into two parts, one part for the digital part and one for the index part. For the sake of understanding, in Figure 2.3 is expressed in decimal, in fact, in the storage un
