The simplest template engine code of the PHP native template engine is as follows: $ A = array ( 'A', 'B', 'C' ); Require 'Template/demo. php'; // reference the template ?> Template File: The code is as follows: Template test The code is as follows: Key value: // Array iteration// Smarty:{Foreach item = na from = $ a key = key}Key Value: {$ key} {/Fore

Analysis 1. Procedure Generally, for a simple program, the Irrlicht engine is generally used as follows: Preprocessing:(1) include the # Include (2) set the namespaceUsing namespace irr;Setting the namespace makes subsequent programming a little easier, just like using the using namespace std; when using C ++ for programming, std: cout (3) notify the compiler to connect to the irr Library File# Ifdef _ IRR_WINDOWS _# Pragma comment (lib, "Irrlicht. li

Decision tree and rule engine, decision tree Rule Engine Use of Decision TreesDecision Trees are often used in data mining and are one of the most basic algorithms. Almost everyone who has learned Data Mining knows decision trees. However, the original use of the restored decision tree is more practical and intuitive when used for decision making or decision-making. Its tree structure guides people to focus

advance, generally need to find an optimal K value through many experiments, and then, The algorithm is less tolerant to noise and outliers, since the algorithm initially adopts the method of randomly selecting the initial clustering center. Noise is the wrong data in a clustered object, and outliers are data that is far away from other data and less similar. For the K-means algorithm, once the outlier and noise are selected as the cluster center at the very beginning, the whole clustering proc

Features of the MyISAM storage table:Use three files per table to save. frm: Table structure definition file. MYD: Table data file, storing data. MYI: Table Index fileInnoDB Storage Table Features:InnoDB When you save a table, you share multiple table data in a tablespace file. This method is not easy to maintain the table. Therefore, it is recommended that each table use a separate tablespace file.Therefore, you need to edit the MySQL configuration file, add the following line:#vim/etc/my.cnfin
