| 摘 要： | 对无序复杂系统的研究,自旋玻璃一直是科学界最具成功的尝试之一。在对复杂事物的认知上,认为真正的复杂性问题只可能以复杂资源进行趋近。基于自旋玻璃的离散特性,首先论证了可以采用元胞自动机来研究自旋玻璃问题;进一步,通过在对一组铁磁与反铁磁材料的实验中,证实了用元胞自动机来解决自旋玻璃问题的可行性;在与模拟退火算法的比较研究中,表明用元胞自动机这一复杂资源探求自旋玻璃问题更具优越性。

| Abstract: | The spin glass has always been one of the most successful attempts in the scientific community to study the disordered complex system.It is considered that the actual complexity can only be approached with the complex resources.Based on the discreteness of the spin glass, this article firstly demonstrates that it is possible to apply the cellular automata to study the spin glass problem.And furthermore,it proves the feasibility through an experiment of the ferromagnetic and anti-ferromagnetic materials.In t... |
