The Scoop: Well, things have been a little damp here in Des Moines, so no _Push Off_ last week (on top of being too busy the previous week). Drake University was more-or-less closed last week, and the phone system was down for most of the time, so I couldn't even dial in. :-( Now we are in limited operation with classes and some offices running. Let's see, we were talking about Vampires and Antivamp. Of course my hope was to completely wipe out vamps - it looks so easy! But CW Blue blew that idea away, his Grimm's Vampyre is riding higher than ever. Some people may have noticed a high-flying imp program making it's appearance in first place, with a VERY high score, which was immediately knocked off by the author. I received this message (names removed to protect the innocent :-) : I have always felt that I was an anti-imp person (This started back when Impire and others first hit the hill, and they started to slaughter my warriors), I always wanted to come up with something to make imps extinct. Now I think I have come up with a better imp/stone......but what do I do???? I hate Imps!!!!! Do I go over to the other side....do I go "If ya can't beat them join them". I don't know Paul, what do I do? Gee, this one's too big for me, what do you all think? I used to think scanners were the enemy, til I figured out how to make Charon a little better. Then there was Hydra, S Linhart's marvelously successful 'multiple bomber' program. Did I see a reference to 'self-regenerating' in there? Anyway, congrats! Seems to be a little succeptible to paper, though. ------------------------------------------------------------------------------- IV.

Other than that, I was playing with some new number theories, but don't have them worked out just yet. Here are some discussion items however. First, if you and your opponent are the same size and bomb at the same rate, one of you may actually have an unbeatable advantage. Here is how it works. Let's say you are both length 100. You bomb forward with a step size of 99, your opponent bombs backward with a step size of 101. You will get whacked first every time because his 101 crosses the gap faster than your 99. If you both bomb the same direction you have a more even chance. So one thing to do is test your step sizes both with addition and with subtraction. Second, the 'optimal' numbers work well because they chunk up large areas of core into smaller and smaller pieces very efficiently. Another way of saying this is that after scanning location N, they will not scan N+/-I, where 'I' is any small number, until very late. A side-effect of this is that they will also not scan N+/-J, where J is any large factor of the core size, until late also. One way for an opponent to take advantage of this effect would be to place components J locations apart. So if you place 4 small bombers at locations 0, 2000, 4000, and 6000, any 'optimally' scanning/bombing opponent will not take out all 4 bombers very rapidly. ------------------------------------------------------------------------------- VII.
