Each path of the s-tree begins at the root node and consists of n+1 nodes. Each of the S-tree ' S nodes have a depth, which is the amount of nodes between itself and the ro

not difficult, but many people lose the score of a question due to memory problems. We need to pay attention to every detail when reviewing the question. dp[x1][y1][x2][y2]=max(dp[x1-1][y1][x2-1][y2],dp[x1-1][y1][x2][y2-1],dp[x1][y1-1][x2-1][y2],dp[x1][y1-1][x2][y2-1])+map

enumerate, to see if all of the pins are selected, then the enumeration of {0, ..., 0} to {1, ..., 1}, which requires 2 of the n-th-exponent. Obviously, when n is large, the efficiency of this approach is very low. The implicit enumeration method introduced in this paper can improve the efficiency of solving the optimal solution.The so-called implicit enumeration method, in the literal sense, is to implicitly remove some cases that do not require enumeration, and from an example, the steps of t

"Problem description" The area near the leader's garden can be pumped into a network of square grids, each corresponding to a coordinate (all integers, possibly negative), if two meshes (x1, y1), (x2, y2) have |x1–x2| + |y1–y2| = 1, the two meshes are

structures. (Ii) fragment sets cannot be described in traditional geometric languages. They are neither trajectory of points that meet certain conditions nor solutions of some simple equations. (Iii) A fragment set has some form of self-similarity, which may be an approximate self-similarity or a statistical self-similarity. (Iv) generally, the "fragment dimension" of the fragment set is strictly greater than its corresponding topological dimension. (V) In most situations of interest, the fragm

Classification algorithm and our life is closely related to the current data mining is the most widely used algorithms, such as: The known series of temperature, humidity sequence and the history of the statistics, we need to use historical data as a learning set to determine whether tomorrow rain, and bank credit card fraud discrimination.Classification problem has a learning set, according to the learning set to construct discriminant function, and finally according to the discriminant functio

In the use of two-dimensional optimization algorithm, it is often necessary to call one-dimensional search algorithm to find the step, while one-dimensional search algorithm needs to determine the search interval. The method can not only be used as a one-dimensional search algorithm, but also can be used to determine the one-dimensional searching interval. The principle of the search interval determined by the Retreat method is: Suppose the one-dimensional objective function is a single-peak fun

the fixed-point function in the book: (define tolerance 0.00001)(define (fixed-point f first-guess) (define (close-enough? v1 v2) ( The fixed-point function uses first-guess as the initial material and calls function f to process it until the input and output values of function f are close-enough. At this time, we will look back at Chapter 1.1.7's function for finding the square root. As mentioned in the book, if we want to find the square root of a number x, we need a y to make y ^ 2
