| 摘 要： | 针对在模量反算中,目标函数在最优值附近表现为大片狭长平坦区域的特点,提出了一类反算新算法——自适应信息遗传算法,新算法的优点是根据信息量大小来进行自适应细分模量解空间,从而节约大量的计算时间.改进了实数交叉算子,使用了新的探险策略,从而加强了新算法后期的局部搜索能力.随后的工程实例表明,这种新机制、新策略的引入,能够在... |

| Abstract: | Due to the existence of a long flat region around the optimum value in objective function for back-calculation of pavement modulus,a new back calculating algorithm,i.e.,adaptive informational genetic algorithm,was proposed.One advantage of the new algorithm is that it can adaptively subdivide the searching moduli space according to the level of information to save a great amount of computing time.A new detective strategy and a modified real-coded crossover operator were used to improve the local search abil... |
