The Second Edition of Applied Optimization with MATLAB Programming enables readers to harness all the features of MATLAB to solve optimization problems using a variety of linear and nonlinear design optimization techniques. By breaking down complex mathematical concepts into simple ideas and offering plenty of easy-to-follow examples, this text is an ideal introduction to the field. Examples come from all engineering disciplines as well as science, economics, operations research, and mathematics, helping readers understand how to apply optimization techniques to solve actual problems.

Optimization is practiced through softwar programsand requiressignificant computer resources. The techniques of optimization havenot changed significantly in centyears but tlle areas ofapplications have mushroomed at a significant rate. Successfullyembedding the use of optimization in professional practice requiresat least three Pquisites.beyinclude mathematical modeling of thedesign problem knowledge of computer programming and knowledge ofoptimization techniques. Many special-purpose optimization softwarepackages relax requiredknowledge of programming are availabletoday. To use them efficiently the remaining two areas still haveto be addressed.

Optimization has become a necessary part of design activity inall major disciplines. These disciplines are not restricted toengineering. The motivation to produce economically relevantproducts or services with embedded quality is the principal reasonforisinclusion. Improved production and design tools wiasynergistic thrust through inexpensive computational resourceshave aided the consideration of optimization methods in newdevelopments particularly engineering products. Even in the absenccof a tangible product optimization ideas provide the ability todefine and explore problems while focusing on solutionsatsubscribeto some measure of usefulness. Generally the use of the wordoptimization implisthc best result under thcircumstances.Thisincludes the particular set of constraints on the developmentrcsources current knowledge market conditions and so on. Every oneof us has probably used thc term at some time to describeeprimaryquality of our work or endeavor. It is probablyemosl used or abusedlerm in advertising and presentations.
