Ah, okay. I thought you meant a tag like on SE.

Where did you get this problem?

#528 Re: Exercises » Bafflers? » 2014-09-12 00:03:29

But what is it needed for?

#530 Re: Exercises » Bafflers? » 2014-09-11 23:30:27

My money is on the one on the right being the gf of two dice being thrown.

#531 Re: Exercises » Bafflers? » 2014-09-11 12:08:37

That factorization isn't quite correct.

#532 Re: Computer Math » Markov chains » 2014-09-11 06:06:18

Okay. Does he have to get those in that order?

#534 Re: Computer Math » Markov chains » 2014-09-11 05:25:38

I need to know if it is enough to reach just one of them before finishing or do you need to get each one separately in multiple goes?

#535 Re: Computer Math » Markov chains » 2014-09-11 05:06:46

Why can you not answer it? I'm asking what the question wants.

#536 Re: Computer Math » Markov chains » 2014-09-11 03:43:27

Yes, I know that, but do you need to reach any of them just once or do you need to get to each one?

#537 Re: Computer Math » Markov chains » 2014-09-11 03:33:19

Just to clear it up, you want to reach 10 the first time, then reach 11 the second time, and so on?

#538 Re: Computer Math » Markov chains » 2014-09-11 03:27:39

Okay. I'll be waiting for it.

#540 Re: Computer Math » Markov chains » 2014-09-11 03:11:33

That would be some mighty casework.

#541 Re: Computer Math » Markov chains » 2014-09-11 02:37:28

Yep. It's like that because of what hapens when B tells the truth. You go from the first state to the third state and C is speaking.

#543 Re: Computer Math » Markov chains » 2014-09-11 02:29:17

Of course. For the big one, the letters stand for prisoners that are still in the game and the asterisks mark the prisoner whose turn it is. B+C stands for any state in which A is no longer in the game and that state is the goal.

For the ssecond one:
ABC - all three are left, A is speaking
AB - A and B left, A is speaking
AC -A and C left, C is speaking
A and B+C the same as in the big one.

Hm, what are your altitude equation?

#546 Re: Help Me ! » coordinate » 2014-09-11 01:17:50

Did you get the answer?

#547 Re: Computer Math » Markov chains » 2014-09-11 01:15:10

The only thing left bugging me is how to bobbym's simulation.

Maybe l, instead of picking them uniformely from the [1,33] interval, we should pick them with some sort of corresponding distribution.

#548 Re: Help Me ! » coordinate » 2014-09-10 12:54:04

What are you stuck with?

#550 Re: Computer Math » Markov chains » 2014-09-10 12:29:46

Hm, you won't be needing all of it at once.

First, take out the rows and columns that correspond to the absorbing states. I'll call that new matrix Q. You need to calculate
