This paper describes a cellular automaton that generates a topological structure for a loading condition. The mathematical model is based on the remodeling (functional adaptation) of biological systems. The model consists of same cells which are mechanically connected with each other. Each cell changes its Young's modulus during sensing of mechanical states around it. Computer simulation showed that the cellular automaton generates many topological structures under the same boundary conditions by changing the distribution of the initial Young's modulus. In order to estimate these topological structures, we proposed a diagram that evaluates the mechanical performance by positioning the structures on a plane with two axes along maximum stress and maximum displacement. The diagram gives us a perspective concept for the design of topological structures.
