In the HGA , heuristic algorithm is used to produced initial population , self-adaptive parameter are used in copy operator, crossover operator and mutation operator .Simulated annealing algorithm is also cited ,and only some excellent chromosomes are operated by SA . In this way, HGA could improve its search ability at cost of a little more run time.

混合遗传算法在产生初始种群时引入启发式方法，采用自适应遗传参数和交替使用两种交叉算子；在搜索方式中加入模拟退火机制，采用只对部分优秀染色体进行退火操作的新策略，这样在保证增强寻优能力的情况下尽量减少运算量。

The method will eventually converge to a near optimal solution and is relatively unaffected by the outliers.Ⅲ. Trilinear geometry estimation based on messy genetic algorithm: similar to the method of epipolar geometry estimation. Experiments show that it is more robust and precise than other typical methods, but takes more time to get the final result.Ⅳ.

ii基于混合遗传算法的对极几何估计：以最小的数据子集来构造染色体，利用染色体在某一位置上的基因冗余来提高遗传算法的选择能力，尽管这样会增加运算的复杂度，但却更有可能寻找到全局最优解，并且运算精度略高于中的算法。
