A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel, equation free, computational methodologies will circumvent this stumbling block, and promises to radically change the modeling, exploration and understanding of complex system behavior. We continue to develop this powerful computational methodology.

工程和科学中复杂系统的一个持久特征是从微观代理（分子，细胞）及其环境的相互作用中出现宏观，粗粒度，连贯的行为。在当前的建模中，从生态学到材料科学，基本的微观机制是已知的，但是将微观尺度知识转化为系统级宏观描述的闭合很少以闭合形式提供。我们新颖的、无方程的计算方法将绕过这个绊脚石，并有望从根本上改变复杂系统行为的建模、探索和理解。我们继续开发这种强大的计算方法。
