like discrete/finite math

- amistre64

if you post a question we can help you better, if possible

- anonymous

I tried that and no one responded lol

- amistre64

well, there are a few answerers and alot of questioners soo, what was the question?

- amistre64

:)

- amistre64

your trying to make pretty matrixes in this thing aitncha

- anonymous

I'm trying to find the negative indicator to this matrix:
4 4 0 1 0 0 0 1
4 1 3 0 1 0 0 1
2 3 3 0 0 1 0 1
-1 -1 -1 0 0 0 1 0

- anonymous

I think that it is in the first column, but which 4 is it?

- amistre64

gonna have to do some reasearch :) what is a negative indicator?

- amistre64

or rather, how are they determined?

- anonymous

you look at the bottom row to see which number is most negative, if there is a tie then you go to the most left number. then you divide the other numbers in that row by 1, and which ever is the smallest is the indicator

- anonymous

which is the point that you pivot around to make all the other numbers in that column zero

- amistre64

how do you tell which number is most negative?

- anonymous

umm, just which ever number is the smallest

- amistre64

so we have 3 -1s in the bottom row here right?

- anonymous

correct, so then since there is a tie for the most negative you choose the one furthest to the left

- amistre64

dividing the number in the row by 1? or by row1?

- anonymous

sorry you divide 1 by the other numbers in the column that the most negative number is in. so it would be like 1/4, 1/4, and 1/2.

- amistre64

ok.... then what :)

- anonymous

then the smallest of those numbers (1/4, 1/4, and 1/2) is the indicator.
but there isnt one that is the smallest

- anonymous

If you don't understand (because I know I'm not explainging this well) you don't have to helping me, I'm sure I will figure it out :)

- amistre64

im perfer helping by osmosis :) just trying to get the juices flowing so that you can solve something you already know...

- amistre64

so you dont divide the 1 by the -1 do you?

- anonymous

nope, just the numbers above it

- amistre64

does the least number work like it did in the bottom and more up or down?

- anonymous

yes, i think

- amistre64

sounds plausible to me.... should we go up or down :)

- amistre64

is there a deeper question that this negative indicator will answer? or aare we simply trying to locate it for posterity?

- anonymous

Haha yes, there is a much deeper question

- amistre64

keep secrets are ya lol

- amistre64

so what is the overall questionthat needs to be answered :)

- anonymous

In an article on the sociology of conflict, the author proposes a game in which a member of a race visits a country in which some natives are pro-green, some indifferent, and some anti-gree. The green visitor, unable to determine which group a native is from, has three options: act appeasing, except civilty but not fight for for it, and expect civilty and fight for it if he doesnt get it.

- anonymous

Then is give the matrix that I gave at the beginning.
What is the visitor's optimum strategy, and what is the value of the game?

- amistre64

so similar to this material?

Yes!

- amistre64

well; you might make better sense of it than me, so i hope it helps :)

- anonymous
