Tic-Tac-ToeThis is a very user friendly tic-tac-toe game with three different difficulty levels. Download the zip file tictactoe.zip then extract the contents in to a folder and in MATLAB run tictactoe.m by typing tictactoe at the command line. You can play against a friend or the computer. The difficulty level can be adjusted in the file menu. The expert level promises to give even the best player a challenge!(This is a very user friendly tic-tac-toe game with three different difficulty levels.

sdemo.m为主文件，界面文件在subf文件夹，snake算法在snke文件夹下，images文件下为测试图片。 此程序以界面的方式展示了Snake算法的分割效果，如果需要做批处理，需要对其改进。(Sdemo. M primarily file, interface file in subf folder, snake algorithm in snke folder, images file for test under the picture. This program to the interface of the way to show the Snake algorithm of segmentation effect, if need to do a batch, needs to be improved.)

This paper presents the simulation of a simple First Order plus Delay Time (FOPDT) process model using advanced control algorithms. Specifically, these advanced algorithms are the IMC-based PID controller, the Model Predictive Controller (MPC) and the Proportional-Integral-Plus Controller (PIP) and their performance is compared with the conventional Proportional – Integral – Derivative (PID) algorithm. The simulations took place using the Matlab/Simulink™ software.
