benchmarkfcns.stepn2

benchmarkfcns.stepn2(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 Step N. 2 benchmark function. stepn2 is an alias for step (De Jong N. 3). Properties:

  • Global minimum: 0

  • Location of global minimum: [-0.5, 0.5)^n

  • Number of dimensions: n

  • Recommended domain: [-5.12, 5.12]^n

  • Modality: unimodal (plateau)
