Date: 15 Jun 1981 0954-PDT From: ISAACS at SRI-KL Subject: re. howtodoit books To: cube-lovers at MIT-AI I haven't seen the Bantom book, but I will keep an eye open. Sigmasters "Notes on Rubik's Magic Cube" is now out and available (at least in the Bay Area), published by Enslow Publishers (Bloy St and Ramsey Ave, Box 777, Hillside, N.J. 07205) , lists for $5.95. Seems to be EXACTLY the "Fifth Edition Preliminary Version", as in a photo-copy, although it may have some minor corrections and changes. There is also a solution booklet by J.G.Nourse, published by Storc, marketed by Paul N. Weinberg, Mountain View, Ca. And still another solution book privately printed by Kirsten Meiers. The solutions (happily) proliferate; each book has variations, most use non-BFUDLR notation - in many cases, just diagrams. Norse intends his solution to be "interruptable" - that is, if you drop the cube in the middle, or get a telephone call (or your computer beeps), you shouldn't have to start over. Meiers is meant to be easy to do. Singmasters ( I think), is meant to be easy to remember - mostly variations on a few basic algorithms. It would be nice to analyse all these solutions and arrange them for speed, ease of action, minimal twists, minimal time, better for right-handers etc.etc. --- Stan -------
