Nonlinear Programming 13
Nonlinear Programming13Numerous mathematical- Programming applications, including many introduced in previous chapters, arecast naturally as linear programs. Linear Programming assumptions or approximations may also lead toappropriate problem representations over the range of decision variables being considered. At other times,though, nonlinearities in the form of either Nonlinear objectivefunctions or Nonlinear constraints are crucialfor representing an application properly as a mathematical program. This chapter provides an initial steptoward coping with such nonlinearities, first by introducing several characteristics of Nonlinear programs andthen by treating problems that can be solved using simplex-like pivoting procedures. As a consequence, thetechniques to be discussed are primarily algebra-based. The final two sections comment on some techniquesthat do not involve our discussion of Nonlinear Programming unfolds, the reader is urged to reflect upon the linear- Programming theory that we have developed previously, contrasting the two theories to understand why thenonlinear problems are intrinsically more difficult to solve.
