The security of the elliptic curve cryptography is built upon the difficulty of solving the elliptic curve discrete problem 椭圆曲线密码系统的安全性建立在椭圆曲线离散对数问题的难解性上。
Since ga could search for a global solution using multiple path and handle discrete problems naturally , it has been developed for solving rpo problem 因能够多路径搜索全局最优解,并可以自然地解决离散性问题,遗传算法被应用到无功优化问题的求解。
However , the optimization methods by simulated evolutions are appropriate for solving the non - linear , discrete problems and combination optimization problems which are difficult to be solved via conventional methods 而模拟进化优化方法最适于解决那些传统优化方法难以求解的高度非线性、离散性问题及组合优化问题。
This method connects the discrete points processed in the level set method to form a smooth curve , thus transforms the discrete problem to continuous one . constraint entry is added to the curve according to the actual demand , and satisfactory result is obtained in experiments . the results show that the algorithm is effective in the actual applications 基于链码的水平集方法把原先水平集方法中处理的离散点,利用链码易于表示曲线的特点,连接成一条光滑的曲线,这样就把离散问题转化为连续问题,利用曲线的连续性和光滑性,根据实际问题的需要,对曲线加入外部约束项控制,在实验中获得了满意的结果,在实际应用中达到了预期的效果。
