Before Change

        a = 20.0
        b = 0.2
        c = 2 * pi

        return (-a * exp(-b * sqrt(sum(x ** 2) / self.N))
                - exp(sum(cos(c * x)) / self.N) + a + exp(1))

After Change

    def fun(self, x, *args):
        self.nfev += 1
        a = (x[0] - pi)**2 + (x[1] - pi)**2
        return -cos(x[0]) * cos(x[1]) * exp(-a)
