Due to the large number of spacecraft members in this type of structure, their optimization can lead to the creation of more efficient and cost effective structures for the use of fossil fuels or even the environment. Hence, the issues of optimizing this type of structure are of great importance. On the other hand, energy is important in the economic development of each country. The purpose of this research is to develop a plan for optimizing high performance spacecraft structures. In the method of optimizing the structures, this action is accompanied by the determination of a group of design variables that, in terms of applied loads, constraints and predetermined parameters, minimize or maximize the target function. Also, in order to validate the spatial structure survey algorithm by examining three numerical examples that are one of the most popular optimization examples and which have been investigated in many valid papers, including the most popular optimization problems for two-dimensional trusses And three dimensional, we find that the most valuable features of the combined method of athletic gradients and chaos theory are that in this way, by narrowing the range of searches, a more precise answer can be obtained. Also, if the optimal solutions for the structure are not within the desired range, the optimal area can be obtained by adjusting the desired range for the answer.
