An improved constraint handling technique based on a comparison mechanism is presented, and then it is combined with selection operator in differential evolution to fulfill constraint handling and selection simultaneously. A differential evolution with two mutation strategies based on this new constraint handling technique is developed to solve the linear bilevel programming problems. The simulation...
The objective function in some real optimization problems may not be differentiable with respect to the unknown parameters at some points such that the gradient does not exist at those points. Replacing the classical gradient search, the method of pseudo gradient search has been proposed and used for solving nonlinear optimization problems, such as nonlinear multiregression based on the Choquet integral...
