benchmarkfcns.hartmann3(arg0: Annotated[numpy.typing.NDArray[numpy.float64], '[m, n]', 'flags.c_contiguous']) → Annotated[numpy.typing.NDArray[numpy.float64], '[m, 1]']

Computes the value of the Hartmann N. 3 benchmark function. SCORES = hartmann3(X) computes the value of the Hartmann N. 3 function at point X. hartmann3 accepts a matrix of size M-by-3 and returns a vector SCORES of size M-by-1 in which each row contains the function value for the corresponding row of X. Properties:

  • Global minimum: approx -3.86278

  • Location of global minimum: approx (0.114614, 0.555649, 0.852547)

  • Number of dimensions: 3

  • Recommended domain: [0, 1]^3

  • Number of local minima: 4

  • Number of global minima: 1

  • Convexity: Non-convex

  • Separability: Non-separable

  • Modality: Multimodal

  • Symmetry: Non-symmetric

  • Differentiable: Yes
