Given the following contour plot, <img src="http://reaskly.com/wp-content/uploads/2022/11/Y5zM1ggmEeigxxLHgCiRzA_1b53d82db11df49952a011d548c90f64_sp1.png"> Which starting points (from 1 to 5) are likely to converge to the global minimum (shown by the mobile phone) when using a steepest descent algorithm?

In this case, the algorithm descends smoothly down the slope.

Again, which starting points converge to the global minimum? <img src="http://reaskly.com/wp-content/uploads/2022/11/KwUUWAgnEei8LQpwydYI3g_79365dd05075a76199e3e4df7a871a44_sp2.png">

This should converge to the global minimum.

From here, the algorithm will descend the hill to the global minimum.

This could be improved by increasing the aggression.

This is causing the algorithm to overshoot. In one case into a different basin.
