Many sorting methods have been discussed before Optimal Sorting. Is there any optimal method? Is there any way to sort the data as quickly as possible? The answer is clearly no. What is the best? A sorting algorithm is affected by many factors. It can also be measured from many perspectives. Some may focus on the number of comparisons, and some may focus on the number of records moving, some of them focus o

We know that looking for a maximum number in a data set with a capacity of N, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of comparisons between the maximum number and the minimum number in a data set with a capacity of N?The Optimal Method for Finding the maximum and minimum n

There are n villages in different coordinates and heights. Now we need to supply water to all the villages, as long as there is a road between the two villages, The distance between the construction pipes is the Euclidean distance between the coordinates (like the Euclidean distance), and the cost is the elevation difference. Now, the solution is required to minimize the cost-to-distance ratio. Obviously, this question requires an optimal rate spannin

For details, please refer to the previous blog: Optimal Huffman coding based on binary tree and doubly linked list for limiting lengthThere is a significant difference in efficiency between array-based and linked-list-based implementations:Encode 256 symbols with a symbol weight of 1 ... 256, limit the length to 16, loop encode 1w times, release mode. Based on the time of the linked list is 8972ms, the array-based time is 1793MS, the speed is 5 times

Huffman TreeIn the general data structure of the book, the tree behind that chapter, the author will generally introduce Huffman (HUFFMAN) tree and Huffman code. Huffman coding is an application of Huffman tree. Huffman coding is widely used, such as JPEG in the application of Huffman coding.First introduce what is Huffman tree. Huffman Tree, also known as the optimal binary tree, is a two-fork tree with the shortest length of a weighted path . The so

There are a lot of articles in the garden about whether the dots are within the triangle, providing various methods. This is very tangled, in the end what kind of algorithm to use? Here is a set of algorithms that I think are optimal. If you have a different opinion, or have a better algorithm, welcome to the discussion.The algorithm uses the same direction method, the principle is: assuming that the point P in the triangle ABC, there will be a rule:

Meaning Give a sequence can S = (e1,e2,..., en), and e1 The binary search tree is recursive in nature, and if its left subtree is not empty, the value of all nodes in the left subtree is less than the value of its root node; if it Right subtree is not empty, the value of all nodes on the right subtree is greater than the value of the root node of the tree. Because in practical applications, the more frequently accessed elements, the closer the root node should be, so as to save more time to

, providing the possibility for faster and farther path searching. The navigation grid in 3D space A * Seek optimization: 1, Memory optimization: In the search for a path, the time spent searching for paths is not the main loss, but rather the memory reset at the start of the route, or the constant allocation and release of memory. As the number of nodes is reduced, the array of nodes (which occupies only 100-200k memory) is established before the path is sought, and a one-dimensional array o

A * algorithm can be used for pathfinding of a single unit. However, in practical applications, multiple units are often moved at the same time, and they will affect each other and hinder the movement of each other. So once the conflict, the path calculated for each unit will be invalidated.A popular solution is to recalculate the path when a conflict is found. There are regular recalculation and so on. These are dynamic adjustment schemes, and the resulting paths are not
