Appendix ALagrangian Methods forConstrained Regional and functional constraintsThroughout this book we have considered Optimization problems that were subject to con-straints. These include the problem of allocating a finite amounts of bandwidth to maximizetotal user benefit (page 17), the social welfare maximization problem (page 129) and thetime of day pricing problem (page 213). We make frequent use of the Lagrangian method tosolve these problems. This appendix provides a tutorial on the method. Take, for example,NETWORK: maximizex 0nr r=1wrlogxr,subject toAx C,posed on page 271. This is an example of the generic Constrained Optimization problem:P: maximizex Xf(x),subject tog(x)= to be maximized subject to constraints that are of two types.
