Sine Cosine Algorithm for Discrete Optimization Problems

Abstract

AbstractIn many scenarios, the nature of the decision-making is discrete and we have to deal with a situation where decisions have to be made from the set of discrete choices, or mutually exclusive alternatives. Choices like passing the electric signal versus not passing the electric signal, going upward versus downward, or choosing a certain route over other available routes are discrete in nature. There are many physical systems for which continuous variable modeling is not sufficient to handle the complexity of the physical systems. For instance, communication models, transportation models, finite element analysis, and network routing models are discrete models. The discrete nature of the search space offers the leverage of definiteness, and possibilities for graphical representation of given particular choices. In fact, discrete optimization problems are of paramount importance in various branches of sciences, like decision-making, information systems, and combinatorics. Operation management decision problems, like product distribution, manufacturing facility design, machine sequencing, and production scheduling problems, fall under the purview of discrete optimization problems. Network designing, circuit designing, and automated production systems are also represented as discrete optimization  problems. Moreover, the application spectrum of discrete optimization  problems includes data mining, data processing, cryptography, graph theory, and many others.
