In design of mechanical components, designer considers objectives that are related with volume, area, quality, cost, etc. of the product depending on the requirements. In the present work, optimization of five stage cantilever beam design problem and three stage heat exchanger design problem is carried using Amended Differential Evolution Algorithm (ADEA). ADEA is modified DE that can handle constrained optimization problems very efficiently. In five stage cantilever beam design problem, the design variables are optimized to reduce the volume of beam and in three stage heat exchanger design problem, the design variables are optimized to reduce total heat transfer area. The results obtained using ADEA are compared with the results reported by other researchers who have used different algorithms, namely, dBA, HS, GA, BA to optimize the same problems. The comparison of results shows that ADEA gives better results for five stage cantilever beam design problem and competitive results for three stage heat exchanger design problem.
