基于细胞分裂中DNA分子的复制机理，提出了一类新的DNA分子双向进化算法算法模拟了一类单亲群体在恒定环境下的双向进化或演变过程论证了在选择机制下，单亲个体能够通过生命进化的基本特征分裂和变异的交互作用，以1的概率演化到环境中的全局最优点文中对算法进行了形式描述和理论探索，给出了收敛性证明通过实例仿真和计算，验证了算法的有效性。

In aIn a11 aspects of GA, including the constraints-handling technique, encoding, fitness function and genetic op-erator, etc, GA is able to provide an alternative optimization technique for constrained problems that are solved in a wlde va riety of domms The penalty one is the most valLd and flexible in the alI techniques, The fundamental methods that can solve the nonlinear programming prohlems in the GA area are reviewed and discussed in tttis paper
