New algorithm need not directly compute values of B-spline interpolatory function, the values were computed using B-spline scaling relation on sampling points, which had simple and uniform coding.
B-spline is the most popular method to present free-form curve and surface, and DP algorithm is the effective approach for solving discrete optimization problems.

The result also reveals that B-spline model performs better than other models integralively in precision of fitting prices, curve smoothness and stability.
