A Review on Bilevel Optimization: From Classical to Evolutionary Approaches and Applications Ankur Sinha, Pekka Malo, Kalyanmoy Deb Abstract—Bilevel optimization is defined as a mathematical program, where an optimization problem contains another op-timization problem as a constraint. These problems have re-
The application of digital computers to the control of scientific instruments has led to the use of stepper motors as a convinient mechanical actuator. We review techniques for driving stepper motors and note in particular new work on providing optimum motor performance with feedback and step division drive systems.
