Prototype optimization design method and system for HPM source

A prototype optimization design method and system for an HPM source, and the method comprises the steps: achieving the parameterization of an HPM source device structure based on the structural features of a to-be-optimized HPM source device type; constructing an auto-encoder based on the change range and precision of the structure parameters; the method comprises the following steps: realizing structure parameter coding by using an auto-encoder, constructing an initial population, and constructing a numerical model of a device described by population individuals by using a decoder and a structure parameter correction method; simulation is completed based on the numerical model, and individual fitness evaluation is completed by using a simulation result; the method comprises the steps that population evolution is achieved through a genetic algorithm with parameter correlation coding introduced, the optimization process is repeated based on the evolved population, and elite individuals are found in an iteratio
