Python Class Constructor: __init__ Method Explained

The __init__ method is the constructor for a class. It is used to initialize the object's attributes when the object is created.

In this case, the __init__ method takes in the following parameters:

• self: A reference to the object itself.
• x0: The initial state of the system.
• u0: The initial control input.
• x1: The desired final state of the system.
• layers: A list specifying the number of neurons in each layer of the neural network.
• dt: The time step for the simulation.
• lb: The lower bounds for the control input.
• ub: The upper bounds for the control input.
• q: The weight for the control input in the cost function.

The purpose of this method is to initialize the object's attributes with the given values.
