SYNOPSIS¶
Classes¶
class
GeneralizedRosenbrockFunction
The Generalized Rosenbrock function in n dimensions, defined by f(x) =
sum_i^{n - 1} (f(i)(x)) f_i(x) = 100 * (x_i^2 - x_{i + 1})^2 + (1 - x_i)^2 x_0
= [-1.2, 1, -1.2, 1, ...]. class
RosenbrockFunction
The Rosenbrock function, defined by f(x) = f1(x) + f2(x) f1(x) = 100 (x2 -
x1^2)^2 f2(x) = (1 - x1)^2 x_0 = [-1.2, 1]. class
RosenbrockWoodFunction
The Generalized Rosenbrock function in 4 dimensions with the Wood Function in
four dimensions. class
SGDTestFunction
Very, very simple test function which is the composite of three other
functions. class
WoodFunction
The Wood function, defined by f(x) = f1(x) + f2(x) + f3(x) + f4(x) + f5(x) +
f6(x) f1(x) = 100 (x2 - x1^2)^2 f2(x) = (1 - x1)^2 f3(x) = 90 (x4 - x3^2)^2
f4(x) = (1 - x3)^2 f5(x) = 10 (x2 + x4 - 2)^2 f6(x) = (1 / 10) (x2 - x4)^2 x_0
= [-3, -1, -3, -1].
