I just noticed a very similar Roman numeral golf recently concluded at golf.shinh.org. Adjusting ySas' winning Perl solution to that game for this one produces this 58 stroker: which has a similar form to robin's early-lead 60 stroker above -- though it uses a different algorithm. Both these solutions are very beautiful, very Perlish, and quite astonishing (at least to me). I especially enjoyed ySas' ingenious use of @- above. I've never seen @- used like that in golf before and am tempted to give it a name, "ySas' device". By way of explanation, note that adding parentheses around (M) above adds one more element to the @- array when the (parenthesized) M matches. That is, the number of items in @- is used to differentiate between a matching M (two items in @-) and a matching D (one item in @-); this fits like a glove here because one and two happen to be the required multipliers. Update: By applying ideas from ySas' solution, we can reduce Robin's original 60-stroker: to 58:
