wife interrupting the thought process every 5 minutes ... under those circumstances one should double the MAX 20 minutes for that teaser ;) --- triple it if 'nagging' was involved ;)) /James

Regarding Spyder's answer to the Einstein Quiz: >That was incredibly hard< Spyder, I thought you said you have a degree. Doesn't that means knowing a little of everything connected to your speciality. I remember one SIMPLE (relative to others) problem: on a table of 'chess' (generally size nxn) place 8 (or n) queens in such a manner that they do not attack each other. The answer was backtracking, and it didn't even involved a computer (one could use one's brain). This problem can too be solved using backtracking and I think the percentage of successes is more that that 15% (and that this 15% should be referred to as "at that time"~"around the '50s"). I'll be glad to hear any other comments or suggestions for other approaches to this problem, Cristian.
