later.Greedy algorithms are still one of the most common algorithms. This is because they are easy to implement and it is not very difficult to construct greedy policies. Unfortunately, it must be proved before it can be applied to the question algorithm.4. backtracking Method: it is an optimization search method that searches forward based on the optimization c

To solve a linear equation group, Gauss-about-extinction (Gauss-jordan elimination) or Kolesky decomposition (Cholesky decomposition) can be used.30, Strukturtensor algorithm -Apply to the field of pattern recognition, for all pixels to find a calculation method to see whether the pixel is in the homogeneous region (homogenous regions), to see if it is an edge, or a vertex.31, merging search algorithm (union-find)-given a

The attentive little partner may have found out that we did not speak the delete operation, because the delete operation involves more things, we speak it sep

the process data in the lookup table is a change, there is a delete or insert operationBinary sort tree: The structure of a tree is usually not generated at once, but in the process of finding it, inserting it when there is no keyword equal to the given node in the tree. The characteristic is that the root node is larger than the left child, smaller than the right child. You can modify the pointer based on the node location when you delete the

the sequence traversal: The left child is less than the left key, the middle child is between key, the right child is greater than the right key Absolute balance: As long as the path from the root node to all the null nodes (we'll talk about how to maintain it later) 2-3 Tree SearchAccording to its characteristics, we can easily know how to find, and the two-fork tree to find almost, just a node more. If the child is smaller than the left: go If less than right child: go m

two are mutually reinforcing and inseparable. On the one hand, algorithms must be implemented with the corresponding data structure. On the other hand, when we define a data structure, we have also defined operations related to it. The steps of these operations are algorithms. In general, this book focuses on the topi

Structure textbooks outside China share a common feature, that is, their first chapter is not about the data structure, but the basic principles of software engineering. I personally think this is very necessary. Especially for most people who have never been familiar with programming, the data structure is the first course that comes into contact with programmi
