New test function to the code base
The function was introduced in Currin et al. (1991)1 as a test function for a metamodeling exercise. The function is a two-dimensional polynomial function defined as follows:
where$\boldsymbol{x} = \{ x_1, x_2 \}$ is the vector of input variables modeled as an independent uniform random vector in $[0, 1]^2$ .
