traditional geometric language, it is neither a locus of points satisfying certain conditions, nor a solution set of some simple equations. (iii) The fractal set has a self-similar form, which may be self-similar or statistically self-similar. (iv) The "fractal Dimension" of a fractal set is strictly greater than its corresponding topological dimension. (v) In most interesting cases, the fractal set is defined by a very simple method and may be generated by the iteration of the transformation.

.(iv) The "fractal Dimension" of a fractal set is strictly greater than its corresponding topological dimension.(v) In most interesting cases, the fractal set is defined by a very simple method and may be generated by the iteration of the transformation.When writing fractal in Java, different graphs call the recursive implementation according to different representations, such as:Koch Curve: Copy Code code as follows: public void draw1 (int x1, int y1, int

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

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

Description "Problem Background" LHX has been plagued by many people who have come to worship him recently, so he added a barrier to his garden. "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

Question: We are in the process of programming, often use to clear screen processing, such as under the DOS under the Cls,turbo C CLRSCR () and so on have clear screen function, but these are the general meaning of the clear screen, Does not show its clear screen rule. And sometimes in order to achieve the clear screen of the artistic beauty, often on the clear screen has some specific requirements, such as: Opening clear screen, closing the screen; on the clear screen; The use of C language t

The usage is simple:Ctx.save () Ctx.beginpath () Ctx.arc (X2,Y2,A,0,2*MATH.PI); Ctx.clip () Ctx.clearrect (0,0,canvas.width,canvas.height); Ctx.restore ();The above code realizes the erase of the circle area, that is, to implement a circular path, then use this path as the clipping region, then clear the pixels. One thing to note is that you need to save the drawing environment first, to reset the drawing environment after you have clear

Poj_1410 Notes: ① The coordinates of the rectangular vertices must be re-sorted and used again. It is only a reference for discuss to say that the top is not strictly above the top, so we need to re-sort and re-use them in the lower order. ② Because the inside of the rectangle is also part of the rectangle, the line segment is considered to be at the intersection of the rectangle in the rectangle. ③ When determining whether the four sides of a line segment and a rectangle have intersecti

random order, so that X is used as a random variable, and the value is equal to the number of times a new office is hired. Then E [x] = Σ xpr {x = x}, but this computation will be very troublesome. We define n variables corresponding to whether or not each candidate is hired, and XI is the indicator random variable corresponding to the event where I candidate is hired. X = X1 + X2 +... + Xn.E [XI] = Pr {Xi} = 1/I, because the applicant is random, so

Main features of this algorithm The problem of two-dimensional cropping is converted into a secondary one-dimensional cropping problem, and the problem of cropping is transformed into solving a set of inequalities; The improvement of the Cohen-Sutherland encoding algorithm is only applicable to the shortcomings of the line segments on the same side (or left, or right, or top or bottom) of the window. The algorithm is divided into one and two dimensions. The former is the basis of th
