Do all possible combinations

you have to list all possibilites

  • lgbasallote
is there any pattern? or are those randomly arranged?
lgbasallote
  • lgbasallote
i can see the first column is organized though

1. toggle the right most variable in every row
lgbasallote
  • lgbasallote
toggle?
ganeshie8
  • ganeshie8
2. toggle the middle variable every 2 rows toggle : T->F or F->T

3. toggle the left most variable every 4 rows

Just have to make sure all of your cases are represented
lgbasallote
  • lgbasallote
will you please elaborate what these "toggle" words that keep popping out on every first word of each step?
ganeshie8
  • ganeshie8
toggle means, if the previous state of a variable is T, change it to F
lgbasallote
  • lgbasallote
what does it mean in video games then?
ganeshie8
  • ganeshie8
if the previous state of variable is F, change it to T
lgbasallote
  • lgbasallote
hmm i see

  • ganeshie8
sometime i get to draw a truthtable with 5-6 variables... this trick helps me
ganeshie8
  • ganeshie8
32 rows, 64 rows... that gets pretty long... but sometimes we have to do it painfully..
lgbasallote
  • lgbasallote
so in four variables T F T F T F T F T T F F T T F F T F T F T F T F T T F F T T F F F F T T F F T T F T F T F T F T F F T T F F T T F T F T F T F T lol
ganeshie8
  • ganeshie8
looks perfect !
lgbasallote
  • lgbasallote
i doubt you read that....
ganeshie8
  • ganeshie8
hey but check the 3rd column is it incomplete or what
ganeshie8
  • ganeshie8
3rd column from right side
ganeshie8
  • ganeshie8
you toggling it every 2 rows, u should toggle it every 4 rows
lgbasallote
  • lgbasallote
wait...i think i may have an idea....
ganeshie8

start with TTTT
myininaya
  • myininaya
I would start a truth table with 4 variables this way: (We will need 2^4=16 rows) TTTT FFFF TTTF FFFT TTFF FFTT TTFT FFTF TFTT FTFF TFTF FTFT TFFF FTTT TFFT FTTF I wrote it like this to show for my last 8 rows I just replaced my T's with F's and my F's with T's that I had in the 1st 8 rows. I said okay also I'm gonna start with 8 T's and 8 F's pattern Then second column I did 8/2 T's and 8/2 F's pattern Third colmn I did 4/2 T's and 4/2 F's pattern And fourth column I did 2/2 T's and 2/2 F's pattern Does that make sense?
lgbasallote
  • lgbasallote
i see...
myininaya
  • myininaya
Like look at the "first column" which is the first 8 rows first
myininaya
  • myininaya
And use what I said
ganeshie8
  • ganeshie8
i do like this usually : 4 variables => 16 rows 1) last column : toggle every row T F T F T F T F T F T F T F T F
ganeshie8
  • ganeshie8
2) 2nd column from right : toggle every 2 rows TT TF FT FF TT TF FT FF TT TF FT FF TT TF FT FF
ganeshie8
  • ganeshie8
3) 3rd columnn from right : toggle every 4 rows TTT TTF TFT TFF FTT FTF FFT FFF TTT TTF TFT TFF FTT FTF FFT FFF
ganeshie8
  • ganeshie8
4) 4th column from right : toggle every 8 rows TTTT TTTF TTFT TTFF TFTT TFTF TFFT TFFF FTTT FTTF FTFT FTFF FFTT FFTF FFFT FFFF

so for 5 variables T T T T T T T T T F T T T F T T T T F F T T F T T T T F T F T T F F T T T F F F T F T T T T F T T F T F T F T T F T F F T F F T T T F F T F T F F F T T F F F F F F F F F F F F F T F F F T F F F F T T F F T F F F F T F T F F T T F F F T T T F T F F F F T F F T F T F T F F T F T T F T T F F F T T F T F T T T F F T T T T looks wrong,,,?
ganeshie8
  • ganeshie8
looks correct but u shouldnt have flipped the second section
lgbasallote
  • lgbasallote
@myininaya 's directions....
ganeshie8
  • ganeshie8
if you're showing first rows as TTTTT, you must show last row as FFFFF
lgbasallote
  • lgbasallote
same shiz
ganeshie8
  • ganeshie8
u can work out using any directions, but the general way we represent truth tables is common everywhere
lgbasallote
  • lgbasallote
order of the first column doesn't matter right?
ganeshie8
  • ganeshie8
what is order ?
lgbasallote
  • lgbasallote
@myininaya 's method is very efficient..i must say
ganeshie8
  • ganeshie8
individual opinion.. i find the method i use is very effecient
lgbasallote
  • lgbasallote
"toggle" confuses me
ganeshie8
  • ganeshie8
i get u :) 'toggle' is industry word.. idk if they use in academic... .
