| This paper presents two meta-heuristic algorithms to solve an extended portfolio selection
model. The extended model is based on the Markowitz's Model, aiming to minimize investment risk in
a specified level of return. In order to get the Markowitz model close to the real conditions, different
constraints were embedded on the model which resulted in a discrete and non-convex solution space.
However, due to the NP-hard nature of the problem two meta-heuristic algorithms were used, namely
the simulated annealing and electromagnetic algorithms. Comparative result indicated high efficiency
of the extended model and the solution presented by the electromagnetic algorithm. |
