When I first used MySQL administrator to create a database, the table is of the InnoDB type by default, so I did not care about it. Later, when using access2mysql to export data, I found that only tables of the MyISAM type can be imported. I checked the differences between the two types. Originally, the MyISAM type does not support advanced processing such as transaction processing, while the InnoDB type does. MyISAM tables emphasize performance, and the execution speed is faster than that of In

DX10 engine plan-bullets and dx10 engine bullets Today, I changed the bullet release mechanism to "collision N times" or "death (suicide)" after a period of time ). The difficulty is to commit suicide. It is difficult to ensure that the system will not "return to Soul" after the suicide ". After searching for a long time, I finally found out which statement is called "soul ": This sentence is the fault. If

Adding a Cache mechanism is perfect! I don't know if the performance of the regular template engine will be higher than that of the template engine. it can be used in self-written programs for convenient calling. Copy codeThe code is as follows: $ A = array ( 'A', 'B', 'C' ); Require 'Template/demo. php'; // reference the template ?> Template File: Copy codeThe code is as follows:

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
