Embodiment Construction
[0067] Now, the method of the present invention is described through the implementation process of specific calculation examples.
[0068] The Multi-Objective ACquisition function Ensemble (MACE) method proposed in this application is compared with other parallel Bayesian optimization algorithms. The methods to be compared include the BLCB algorithm proposed in the prior art [8], the local penalty (LP) algorithm proposed in the prior art [9], the qKG method proposed in the prior art [10] and the prior art [ 11] proposed qEI method.
[0069] The present invention uses three calculation examples to test the MACE algorithm. The first calculation example is a general analytical test function, and the other two calculation examples are actual analog circuit netlists, including an operational amplifier and a power amplifier.
[0070] Implementation example 1
[0071] Eight general analytical test functions are used to test the MACE algorithm. The dimensions and computational searc...
