Ridurre il sale: una proposta per tuttihe design space. The set . may be defined by equality or inequality constraints, and these constraints may assume linear or nonlinear forms. The function . together with the set . in the domain of . is called a . or a mathematical programming problem. This terminology is in common usage in the conte

Although most structural optimization problems involve constraints that bound the design space, study of the methods of unconstrained optimization is important for several reasons. First of all, if the design is at a stage where no constraints are active then th
