Abstract: A method, apparatus, computer device, and storage medium for automatic design of analog circuits based on tree structure. The method includes: setting the maximum height and growth direction of the tree structure; randomly calling the node from the function node library as the parent node; randomly calling the node from the function node library and the port node library as the child according to the growth direction node; if the child node is a terminal node, generating a tree structure; checking the tree structure, if the tree structure satisfies the preset conditions, obtaining the circuit topology and device parameter that conform to the circuit rules; evolving the circuit topology and device parameter to generate an analog circuit. The embodiments achieve the effect of making the tree structure of the designed analog circuit more reasonable.

Abstract: An optimization method, apparatus, computer device and storage medium for engine model. The method includes: setting an initial population according to a predetermined number of solutions; obtaining a first output set of the initial population on the engine model; determining a first fitness value; operating selection, crossover, and mutation on the initial population according to the first fitness value to obtain an evolved population, and the initial population and the evolved population constitute a to-be-selected population; obtaining a second output set of the evolved population on the engine model; determining a second fitness value; selecting engine model parameters in the to-be-selected population to form a new population according to the second fitness value; and optimizing the engine model by using the engine model parameters in the new population if a termination condition is met.
