Computational optimization is pervasive in various functions in engineering and production. In this paper, the details about computational optimization, optimization algorithms generally in use, modeling techniques, and the simulation. Computational optimization is an integrated part of new design practice that is extensively utilized in design applications of engineering and industrial. Products and facilities are often related to the profits escalation and cost reduction but also intend at being further energy-efficient, ecological, and safer as well as they are limited by time, resources, and amount. We will analyze the recent tendencies in optimization, and modeling and the parts of a typical optimization process to identify optimal results efficiently are discussed in this paper.
