Before revision: Design optimization problem The formal mathematical (standard form) statement of the design optimization problem is where is a vector of n real-valued design variables is the objective function are equality constraints are inequality constraints is a set constraint that includes additional restrictions on besides those implied by the equality and inequality constraints.
