benchmarkfcns.kowalik(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 Kowalik benchmark function. SCORES = kowalik(X) computes the value of the function at point X. kowalik accepts a matrix of size M-by-4 and returns a vector SCORES of size M-by-1. Properties:

  • Global minimum: 0.0003075

  • Location of global minimum: (0.1928, 0.1928, 0.1231, 0.1358)

  • Number of dimensions: 4

  • Recommended domain: [-5, 5]^4

  • Modality: multimodal
