Re: Cow Bull 1

Hmm. I thought that because the guess was redundant last time, you made it the number this time. Oh well, I suppose I'd better win it now.

Guess 8: 3614


Why did the vector cross the road?
It wanted to be normal.

Re: Cow Bull 1

Can you check your answers please? I worked it through logically, and 3614 should be the only answer, when given the information up to guess 7. I've double-checked my working, and I didn't find any mistakes, although that doesn't mean there isn't one.

Re: Cow Bull 1

Okay, I've checked and everything seems to be in order. That is, I think everything is right. I may be wrong, of course.

Let me just say that your 'logical' post (#100) was [very maybe] not so logical, and there might be another option. Especially in the first sentence of the second paragraph. Presuming everything up to now is right. Sorry if I'm wrong. big_smile

It's all right. 'Tis better to ask questions than be confused. big_smile

I'm willing to bet that by the time I've posted this post you'll have probably have posted the correct answer.

Re: Cow Bull 1

He's got a program doing all the number logic for him and sometimes he inputs the wrong numbers.  Always copy/paste mathsy!

There's a problem ... make a program that gives guesses, well, logical guesses based on past ones.

In the meanwhile, I'm thinking of a number between 1023 and 9876 ... without repeating any digit.  Using ten-sided number generators, if that helps.

Okay, lets admit and concede, Mathsy is too good at it....
I throw open a challenge....
Someone guess this within 5 guesses.....

Re: Cow Bull 1

It doesn't matter yet, but if we are going to get this under five guesses, it might be a good strategy to wait for the reply first. Then we can consider all the information! big_smile

Yes, that's right. And then we still get to find the answer but we get to keep one of our guesses!

Re: Cow Bull 1

jU, give him time, I'm sure he'll reply soon enough. He may also be very busy, so we have to keep that in mind. You can sit back and relax!
