intelligent p id

Inspired by the laws of human intelligence, biological community or natural phenomena, many intelligent optimization algorithms have been invented, which mainly include: (1) Genetic algorithm: imitating the biological evolution mechanism of nature (2) Differential Evolution algorithm: Optimizing Search through cooperation and competition among groups of individuals (3) Immune algorithm: Simulated biological immune system learning and cognitive func

for an experienced developer to automatically generate query results based on the query conditions on the HTML page. The simplest is to traverse the submitted Query Form and connect it into an SQL statement for query. However, SQL has many problems.
