而由于黎曼积分具有局限性，黎曼积分只能用于连续函数类的积分。

And because of the limitations of Riemann Integration, it can only be used for continuous function.

针对这类问题和现有连续函数模拟退火算法的某些不足，本文给出了一类改进的模拟退火算法。

Regarding of the characters of this class of problems and the disadvantages of the existing simulated annealing algorithms, we propose an improved simulated annealing algorithm.
