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, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.

工程和科学中复杂系统的一个持久特征是，微观主体（分子、细胞、颗粒）及其与环境的相互作用会出现宏观、粗粒度、连贯的行为。在当前的建模中，从生态学到材料科学，底层的微观机制通常是已知的，但将微观知识转化为系统级宏观描述的闭包很少以封闭形式提供。我们的新颖方法将探索这个绊脚石，并有望从根本上改变多尺度复杂系统行为的建模、探索和理解。
