Detailed Description

Implements the Woods test function.

Here the goal is to find a parameter set that minimises the Woods test function (four dimensions). This function is defined as:

residuals[0] = 10.0*(B - A*A); residuals[1] = 1.0 - A; residuals[2] = sqrt(90.0)*(D - C*C); residuals[3] = 1.0 - C; residuals[4] = sqrt(10.0)*(B + D - 2.0); residuals[5] = (B - D) / sqrt(10.0);

The goal is to find the values of A, B, C & D that give a minimum cost. In terms of the model, A = param[0], B = param[1], C = param[2], and D = param[3].
