Currently,computational simulation techniques,playing an significant role in the design and optimization of complex engineering systems,have been making a notable progress in simulating the true physical problem.However,optimization requiring expensive time cost and computational resource,is still prohibitive.Surrogate model technique is a kind of fast-solving and data-based method which is used to approximate the formula-undefined problem.It is well to be reminded that surrogate models are often implemented in code in a variety of software,making it very inconvenient for designers to use.
