Optimization Problems Solving with Using of Discrete Harmony Search Algorithm: A Review

It is usually assumed the variables which are used in the optimization problems are continuous variables. However, the variables have discrete or integer values in many real life practices. Considering discrete integer variables in the optimization problems makes the problems more complex. There are few methods to solve these type of problems.The Harmony Search Algorithm inspired by improvisation of musical harmony and a recent variant of it, The Discrete Harmony Search Algorithm were investigated. It is thought that The usage of the Discrete Harmony Search Algorithm is going to provide a good alternative to solve the optimization problems.
