计算存在在电力市场的现货市场的现货价格、社会福利(calculate some parameter in spot market)

说明：  LMS/F组合算法由Shao-jen Lin和J.G.Jarris提出，它计算量增加不多却同时兼有LMS和LMF算法的优点。即收敛速度和稳态性能比基本LMS算法好，稳定性比LMF算法好。(LMS/F combination algorithm by the Shao-jen Lin, and JGJarris proposed, it is increasing much more calculations with both LMS and the LMF of the method. Ie, the convergence speed and steady-state performance better than the basic LMS algorithm, stability, better than the LMF algorithm.)
