Elliptic Partial Differential Equations,In this chapter we review the main tools used to study elliptic partial differential equations (PDE): Sobolev spaces, variational formulations, and continuous dependence on the data.

Optimization Methods,In this chapter we review the classical algorithms of optimization which are used in the numerical solution of shape design problems. For unconstrained minimization problems, the most widely used algorithm is the conjugate gradient method; however, it is best to begin with the method of steepest descent and Newton’s method.

Other Methods,0], [61] and the method of characteristic functions [18], [63]. These methods lead naturally to numerical algorithms using the finite difference method. Thus, finite difference solutions of shape design problems as studied in [18], [48], [35] are also presented here. Finally, we also analyze the feasibility of the boundary element method.
