A new way is presented to solve the asynchronous execution problem and black screen problem when the FORTRAN's executable files are used by the shell func-tions. Finally, an example of the optimization system is given to verify the method's feasibility and validity. 对外壳函数调用FORTRAN生成的可执行文件时系统出现的异步执行问题和黑屏问题提出了解决办法,最后给出了优化系统的设计实例,验证了该方法的可行性和有效性。
By Feynman_Kac's theorem in stochastic differential engineering, we obtain the Black_Scholes'pricing formula of European option underlying stock. This pricing method can be used in other options pricing models as well. 直接利用随机微分方程的FeynmanKac定理推导出欧式股票权定价的BlackScholes公式,这种方法还可推广用于其他期权的定价。
