In the absence of ocular dominance, conjugate gradient iteration applied to a certain objective function formulation reproduces the characteristic orientation preference map structure previously derived from a related dynamical system approach on a coarser cortex mesh. Numerical experiments indicate a strong sensitivity to the line search parameters and direction update, demanding careful consideration. References- G.
