Versatility of Simulated Annealing with Crystallization Heuristic: Its Application to a Great Assortment of Problems

By Tiago G. Goto, Hossein R. Najafabadi, Guilherme C. Duran, Edson K. Ueda, André K. Sato, Thiago C. Martins, Rogério Y. Takimoto, Hossein Gohari, Ahmad Barari and Marcos S.G. Tsuzuki

This chapter is related to several aspects of optimization problems in engineering. Engineers usually mathematically model a problem and create a function that must be minimized, like cost, required time, wasted material, etc. Eventually, the function must be maximized. This function has different names in the literature: objective function, cost function, etc. We will refer to it in the chapter as objective function. There is a wide range of possibilities for the problems and they can be classified in different ways. At first, the values of the parameters can be continuous, discrete (integers), cyclic (angles), intervals, and combinatorial. The result of the objective function can be continuous, discrete (integers) or intervals. One very difficult class of problems have continuous parameters and discrete objective function, this type of objective function has very weak sensibility. This chapter shows the versatility of the simulated annealing showing that it can have different possibilities of parameters and objective functions.
