[Click on image for larger view.] Figure 1: Using Spiral Dynamics Optimization to Solve the Rosenbrock Function. The Rosenbrock function with dim = 3 has a known solution of 0.0 at (1, 1, 1). The demo ...

The input argument fun refers to an IML module that specifies a function that returns f, a vector of length m for least-squares subroutines or a scalar for other optimization subroutines. The returned ...

The graph in Figure 2 shows the Rosenbrock function for dim = 2 where the minimum value is 0.0 at (1, 1). The Rosenbrock function is challenging because it's easy to get close to the minimum but then ...
