Yeah same here(although 8, 10 and 16 seem easily doable); number 3 is a pretty simple cryptography sequence. Some of the other ones, though, look like they require a significant amount of mathematical experience and/or the use of computer tools.

It was #10 that made look up this test, I have yet to solve it or even see a solution to it. My guess is its an  NP complete problem such as the traveling salesman.


Just Got 16

Actually, you already know enough to "solve" #10. Which is to say, it is a trick question. Electrical Resistance relates to how resistant a material is to an electrical current. A current must have physical space to travers. No material can exist at 2-Dimensions, therefore there is no material for the current to travel through (indeed, there isn't even room for the current itself to exist). The resistance is then nonexistant, or effectively the answer is "infinitely resistant." No electicity will ever travel between two nodes along a 2-dimensional plane... I think.

That all hinges on the usage two dimensional, if they mean it literally then Thought is correct. I think what was intended was that it doesn't grow in depth, or its stays a grid or "lattice" not a cube or web or resistors. The fat that it is infinite would just mean its all flowing equally. Two adjacent would be simple, but after that I haven't a clue how to go one.


This was how I heard about the question and how I found the test

10 is certainly not impossible; here's how to set it up(without giving the solution): http://www.geocities.com/frooha/grid/node2.html

Still working on 16, though...Edit: I have to work with Soddy circles?! :x

Edit: number 8 is so easy...

That is the answer for two resisters diagonal from each other its a common problem, read it a again a knights move away.




Got 20, My brother said 96 "just sounded right" then it hit me.

Not that hard to do; just substitute in a knight's move(e.g. m+2, n+1).

Given that the "test" is largely creative and subjective in nature, I am rather dubious that the straight up mathematical questions are really straight up or mathematical (yes, including #3. Getting the answer is easy, properly displaying that answer is a bit more tricksy).

I think it would be acceptable to display it like:
[spoiler]s0: 1
s1: 1x1
s2: 2x1
s3: 1x2, 1x1
s4: 1x1, 1x2, 2x1
s5: 3x1, 2x2, 1x1 or 312211

Well crap, it looks like I was making things more complex than they needed to be. I had:


1=1
11=2
21=3
1211=5
111221=8
???=13
???=21
???=etc

As 1+2=3, 2+3=5, 3+5=8, and 8+5=?, and the number of possitions on each line goes 1, 2, 2, 4, 6, then presumably 8 and 10.

Thefore I was coming up with somthing closer to 32221111, followed by 12223232221, but your way makes the display much easier.

BROJ thats the same as what I got.

20 was rather unique, I wouldn't have gotten with out my brothers comment.

[spoiler]

ten=3
nine=4
sixty=5
ninety=6
seventy=7
sixty six=8
ninety six=9
[/spoiler]

Yeah 20 was more of a logic problem.

Here's what I got for 8:
[spoiler]
320=3486784401[/spoiler]

On an unrelated note: I just finished, in SO2, transfering Dias' data from a Rena scenario to a Claude scenario using a hex editor as well as Claude still has his 'Phase Gun' tech; if anybody wants the save file let me know.
