Self-Adaptive Genetic Algorithm for Clustering 总被引:6,自引:0,他引:6
Clustering is a hard combinatorial problem which has many applications in science and practice. Genetic algorithms (GAs) have turned out to be very effective in solving the clustering problem. However, GAs have many parameters, the optimal selection of which depends on the problem instance. We introduce a new self-adaptive GA that finds the parameter setup on-line during the execution of the algorithm. In this way, the algorithm is able to find the most suitable combination of the available components. The method is robust and achieves results comparable to or better than a carefully fine-tuned non-adaptive GA. 相似文献

The characterization of chaotic spatiotemporal dynamics has been studied for a representative nonlinear autocatalytic reaction
mechanism coupled with diffusion. This has been carried out by an analysis of the Lyapunov spectrum in spatiallylocalised regions. The linear scaling relationships observed in the invariant measures as a function of thesub-system size have been utilized to assess the controllability, stability and synchronization properties of the chaotic dynamics.
The dynamical synchronization properties of this high-dimensional system has been analyzed using suitable Lyapunov functionals.
The possibility of controlling spatiotemporal chaos for relevant objectives using available noisy scalar time-series data
with simultaneous self-adaptation of the control parameter(s) has also been discussed. 相似文献
