1.2 compare steepest descent optimal step with conjugate gradient, larger range

The objective function is \(f(u) = (11-u_1-u_2)^2 + (1+u_1+10 u_2-u_1 u_2)^2\)

This is the same as the earlier animation but uses larger range. Starting from \(u^0=\{14;23.59\}\).

steepest descent, optimal step size, 76 iterations

conjugate gradient, Polak-Ribiere formula, 14 iterations. Completes much faster with less itreations.
