| Abstract: | A stochastic model is given for portfolio selection by the probability measure and confidence level.The difference solutions are obtained based on random variable distributing,namely,the conventional optimization algorithm and the equivalent linear programming algorithm.The experiment results show that the proposed algorithm is simple and feasible,and has practical value. |
