benchmarkfcns.multiobjective.oka1(x: Annotated[numpy.typing.NDArray[numpy.float64], '[m, n]', 'flags.c_contiguous']) → Annotated[numpy.typing.NDArray[numpy.float64], '[m, n]']

Computes the value of the OKA1 bi-objective benchmark function. SCORES = multiobjective.oka1(X) computes the value of the OKA1 function at point X. multiobjective.oka1 accepts a matrix of size M-by-2 and returns a matrix SCORES of size M-by-2. Properties:

  • Recommended domain: x1 in [6*sin(pi/12), 6*sin(pi/12) + 2*pi*cos(pi/12)], x2 in [-2*pi*sin(pi/12), 6*cos(pi/12)]
