Design. The fundamental construction and linear induction motor design almost correspond the same as three-phase induction motor, even though it does not appear like that of a normal induction motor. When a cut is formed in the stator section of the polyphase induction motor and placed on a flat surface, then this creates the primary section of the linear induction motor.

The setting of parameters in the support vector machines (SVMs) is very important with regard to its accuracy and efficiency. In this paper, we employ the firefly algorithm to train all parameters of the SVM simultaneously, including the penalty parameter, smoothness parameter, and Lagrangian multiplier. The proposed method is called the firefly-based SVM (firefly-SVM).
