benchmarkfcns.shekel7(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 Shekel-7 benchmark function. SCORES = shekel7(X) computes the value of the Shekel-7 function at point X. shekel7 accepts a matrix of size M-by-4 and returns a vector SCORES of size M-by-1 in which each row contains the function value for each row of X. Properties:

  • Global minimum: approx -10.4029

  • Location of global minimum: (4, 4, 4, 4)

  • Number of dimensions: 4

  • Recommended domain: [0, 10]^4
