Non-dominated sorting is widely used in multi-objective evolutionary algorithms. There are many approaches to non-dominated sorting, but they are computationally expensive when the number of objectives or the number of fronts becomes relatively large. This paper proposes an efficient non-dominated sorting approach based on a dominance ranking graph created in this paper. The approach takes advantages of both the dominated and non-dominated relationships, it is able to efficiently handle the case of large number of objectives/fronts. Experimental results show that the proposed algorithm outperforms its several popular variants in most of the tests.

This paper proposes a new image restoration technique, in which the resulting regularized image approximates the optimal solution steadily. The affect of the regular-ization operator and parameter on the lower band and upper band energy of the residue of the regularized image is theoretically analyzed by employing wavelet transform. This paper shows that regularization operator should generally be lowstop and highpass. So this paper chooses a lowstop and highpass operator as regularization operator, and construct an optimization model which minimizes the mean squares residue of regularized solution to determine regularization parameter. Although the model is random, on the condition of this paper, it can be solved and yields regularization parameter and regularized solution. Otherwise, the technique has a mechanism to predict noise energy. So, without noise information, it can also work and yield good restoration results.

提出一种用多目标技术求解约束优化问题的算法.该算法有3个特征:1)将约束优化问题转化为等价的动态约束多目标优化问题,然后用动态约束多目标演化算法求解动态约束多目标优化问题;2)演化初始阶段,拓宽约束边界以使整个种群可行;演化过程中,约束边界微弱的收缩以确保动态约束多目标演化算法中种群的大多数个体仍是可行的,这使动态约束多目标演化算法如同多目标演化算法求解无约束问题一样有效;3)采用基于学习的机制自适应调整演化算法的参数,以提高算法效率.实验结果表明,与4个当前较为先进的约束处理算法相比,本文算法效果更优.
