\(200 / 2^{j-1}\), where \(j\) is the interaction degree. We also
include some other suitable settings for <code>num_knots</code> below, all of
which are less complex than default <code>num_knots</code> and will thus result
in a faster runtime:</p><ul><li><p>Some good settings for little to no cost in performance:</p><ul><li><p>If <code>smoothness_orders = 0</code> and <code>max_degree = 3</code>,
