ST table (Spars table) of doubling ideas and data structures **ST table is a data structure based on the idea of doubling and used to solve the problem of repeatable contribution. ** First, understand what the idea of doubling is. The doubling algorithm, as the name suggests, is to multiply by a power of 2. […]

Basic algorithm ideas (2)
Recursive algorithm 1. Overview of Recursive Algorithm Recursion/recursion can be understood as both an algorithmic idea and an algorithm implementation method. The divide-and-conquer algorithm strategy is mainly implemented through recursion, and large-scale problems are decomposed into small-scale problems; the dynamic programming algorithm is mainly implemented through recursion The core of recursion and recursion is actually […]
MySQL face vector, Euclidean distance similarity query
Foreword For example, the title uses the extracted face feature vector to write a Euclidean SQL statement to query the top_K data records with the highest similarity in the database. Although the approach is alternative, there is a ready-made facial retrieval API on the market at the business layer, and there is now a vector […]

Algorithm: Explanation of dynamic programming ideas (C/C++)
I accidentally reviewed the review with my colleagues two days ago and found that the algorithms in the previous functional business were really unsightly. The entire algorithm structure exceeds 50 lines…all if, else. The main focus is a customized explanation of a special problem, but this also exposed multiple problems. In fact, in many development […]
