are more obvious. If it is a long method, the JVM may just kneel down. The second reason is more important: Method inline If the JVM detects that some small methods are frequently executed, it replaces the method call with the method body. For example, the following: private int add4(int x1, int x2, int x3, int x4) {return add2(x1, x2) + add2(x3, x4);}private int add2(int x1, int

traversed, as the "stage" of DP. "The path length is n+m-2" because it can only go down or to the right (N,M)In each phase, the two paths are expanded one step at a time, and the path length is increased by 1, thus moving to the next stage.You also need to determine the current end position of the two path. and x1+y1 = x2 + y2 = i + 2So you can use three-dimensional DP maintenance, there are 4 ways to expand each time. and consider whether the two po

calculate the frequency of each sentence by counting the sentences appearing in the dataset, the number of occurrences C (x), and the total number of sentences in the dataset. X∈s,p (x) = C (x)/n indicates the frequency of X, apparently σp (x) = 1.In summary, we can find a few questions:1) The above language model only exists theoretically, when the training data set is infinitely large, the frequency of the data set can be infinitely close to the actual probability in the grammar;2) for most s

C # has three operators: unary operations, two-dollar operations, and three-dimensional operations. The so-called two-dollar operation is to participate in the operation of the variable has two, the other two analogy. A Mathematical operations One dollar includes: +,-,++ and--。 such as: int x=10; int x1=+x;int x2=-x; so x1=10;x2=-10. These two operations are relatively simple. Binary operation: Add, sub

Chi-square test or chi-square test The Chi-square test (chi-square test) or chi-square test is a widely used hypothesis test method. It can be divided into two types: group comparison (non-paired data) and individual comparison (matching, or comparison of the same object.
