摘要

The investment on real estate companies has a direct impact on the competitiveness of their future markets; therefore there is an urgent need for investment portfolio optimization. The paper analyzes the characteristics of various types of real estate investment in the next run, using niche genetic algorithm with improved the probability of crossover and mutation. In addition, adding the budget constraints in the classic portfolio model, so that the process of calculating is more to meet realistic requirements. Finally, an example is used to prove the method is effective.
