This instructions seem incomplete.

Consider a tower of three, moving from the left to right:

321 / - / -

32 / - / 1

3 / 2 / 1

Next, 1 should be moved to the center position on top of two for the optimal solution, but your ruleset has no indicator of which choice should be made.

You're right, how can we simplify that into a usable insite?

Prioritize erecting "neat" towers then moving the largest disk not placed in the previous step?

For each tower of size N, move tower (N - 1) to the non-target position, then move the base to the target position, then move the previously moved tower of size (N - 1) to the target position.
