Which specific exercise or problem from _TAOCP Volume 4_ (and which section / fascicle) would you like solved?

Section 7.2.2: Backtracking

Exercise 60. ▶ [20] Experiment with biased random walks (see exercise 54), weighting each non-dead-end king move to a new vertex $v$ by $1 + \text{DIST}(v)^2$ instead of choosing every such move with the same probability. Does this strategy improve on Fig. 70?
