Solving Constrained Mean-Variance Portfolio Optimization Problems Using Spiral Optimization Algorithm

Abstract: Portfolio optimization is an activity for balancing return and risk. In this paper, we used mean-variance (M-V) portfolio models with buy-in threshold and cardinality constraints. This model can be formulated as a mixed integer nonlinear programming (MINLP) problem. To solve this constrained mean-variance portfolio optimization problem, we propose the use of a modified spiral optimization algorithm (SOA). Then, we use Bartholomew-Biggs and Kane’s data to validate our proposed algorithm. The results show that o… Show more

“…This strategy is better than handling the integral constraints using penalty in the objective function, because it will require a lot of resources to find a near optimal solution. For example, Febrianti et al (2022) used a population of 50,000 elements in solving a constrained portfolio optimization consisting of only 5 assets.…”
