This paper proposes a Sine Cosine hybrid optimization algorithm with Modified Whale Optimization Algorithm (SCMWOA). The goal is to leverage the strengths of WOA and SCA to solve problems with continuous and binary decision variables. The SCMWOA algorithm is first tested on nineteen datasets from the UCI Machine Learning Repository with different numbers of attributes. instances. http://www.roneverhart.com/Hanes-Perfect-T-Triblend-T-Shirt-True-Green-Heather-Hanes-42TB/
