As efficient methods of reducing the investment risks, the real estate portfolio optimization methods and models have some defects. The information entropy was used as the risk measuring index, and a self-adaptive ant algorithm with a changing index was proposed to overcome the deficiency of the basic ant algorithm. Then the improved algorithm was introduced into the real estate portfolio. And the...
The purpose of this paper is to propose an improved algorithm to overcome the premature deficiency of the basic ant algorithm, which is a novel simulated evolutionary algorithm, also a newly stochastic and intellectual searching optimization. After systematically analyzing the basic knowledge of the basic ant algorithm-ant system algorithm, an improved ant algorithm with a strategy of changing index...
