How many Numbers puzzles are there in total?
Is there a way you can work out the amount of countdown numbers games? I know there are 24 numbers to pick from (two each of numbers 110 and 25, 50, 75, 100) and I think you work out the amount of numbers combinations (which is the part I don't know how to do) and then multiply by the amount of targets which is 898 I think (999101=899 ).
Does anyone know how to work out the amount of possible numbers combinations? I know there are 24 numbers and 6 numbers in a game obviously. It wouldn't be 999,999 surely because those are just the numbers 09 (10 numbers) and there are six of one number each (filling all gaps). In this case, there are two of numbers 110 each and 25, 50, 75, 100.
Hope you all get what I mean, apologies if I haven't been clear.

Re: How many Numbers puzzles are there in total?
There are 2850 possible 6 smalls, 5808 of 1 large, 3690 of 2 large, 840 of 3 large and 55 of 4 large, so 13243 different selections in total.
As to how to work it out, it's all about factorials. For example, the number of 6 small is 10!/(6!4!) plus 10!/(5!5!) x 5!/(1!4!) plus 10!/(4!6!) x 4!/(2!2!) plus 10!/(3!7!). And it really is as simple as that.

Re: How many Numbers puzzles are there in total?
Right. I'm probably gonna make about a hundred arithmetic errors and someone will answer as I type this as it's been up for over an hour but let's have a crack.
As you say, there's 899 targets so just multiply the amount of selections by 899 to get your answer.
I'd go about it by splitting the selection into the different types.
With 4L, the only thing that can change are the two smalls (assuming when the numbers are the same but in a different order it counts as the same puzzle. If not, then do some shit with factorials). There are 55 different small selections you can get (and thus only 55 different 4L selections, so hardcore 4Lers could literally learn all targets available with each of the 55). This is because there's 10x10=100 ways to pick two small. Ten are going to be the same number twice, and the other 90 are going to all have the reverse in it (so 2, 3 and 3, 2 are both given). You can thus get rid of half the 90, making 10+45=55. I use that idea for the rest of them.
OK, so 55 4L selections. Moving onto 3L. There's four different ways of doing the larges, cause each one will be missing one of the four larges. With the smalls, you have 3 smalls which can either be two of the same and another one, or three different ones. (Thanks god I'm not working out the chance of each cause that'd be a right ballache.) The first scenario is 90 combinations as it's like the thing I did earlier except you can't have two (three) of the same cause there's only 2 of each number, and you can't get rid of half as 2, 2, 3 is different to 3, 3, 2. The second scenario is just 10 choose 3 = 10!/(3!*7!) =120. Adding them gives 210 ways of doing 3 smalls, multiplied by 4 for the larges, gives 840 different possible 3L selections.
2L time. There's 6 ways of doing the larges (25 50 , 25 75 , 25 100 , 50 75 , 50 100 , 75 100). The smalls can either be:
4 different ones (10 choose 4 = 210)
Two pairs (just 10x9/2=45 (10 choose 2) using stuff from earlier, and 2233 is the same as 3322 but 1111 can't exist)
One pair and two different ones. Ten different options for the pair and then 9 choose 2 for the other two = 10*36=360. That gives you 360+210+45=615 ways of doing 4 smalls, times 6 which gives you 3690 different 2L selections.
Gee I've probably made a really stupid maths error somewhere
1L There's obviously 4 different ways of doing the larges. Smalls:
Two pairs one singlet (10c2 times 8c1 =45*8=360)
One pair three singles (10c1 times 9c3 =10*84=840)
Five singletons (10c5=252)
Adding them gives 360+840+252=1452 ways of 5 smalling times 4 is 5808 1L selections
Six small. This selection should be illegal but it isn't so
Three pairs = (10c3=120)
Two pair two single = (10c2*8c2=45*28=1260)
One pair four single = (10c1*9c4=10*126=1260 again, spooky)
Six single = (10c6=210)
Add them = 2850 six small selections. All of them suck.
I probably mathsed everything wrong
Add them all is 55+840+3690+5808+2850= 13,243 numbers selections.
Times the targets and you have 13,243*899= 11,905,457 of whatever I was working out.
Now to look over all the mistakes I've made
Edit: Fuck's sake Fred

Re: How many Numbers puzzles are there in total?
Oh yeah there are 899 targets, so 999100=899. Silly me haha.
That must be right considering you both got the same answer with different methods. Thanks both Fred and Thomas!
How long did it take you to do that Thomas haha?

No, just this one, and quite a bad one as well.Thomas Carey wrote:Right. I'm probably gonna make about a hundred arithmetic errors
Seeing as I'm too thick to understand Fred's method and probably won't live long enough to read through Tom's, I'll present my own alternative method. Instead of going through each of the numbers types individually, I'm going to look at it in terms of how many pairs of repeated numbers there are. There can be 0, 1, 2 or 3 in a numbers game.
0 repeated numbers: I'm not making any distinction between large and small, so there are 14c6 (14 choose 6) combinations with no repeated numbers, which equals 3,003. I'll save the multiplication by 899 until the end to make things easier.
1 repeated number: 10 possibilities for the repeated number, multiplied by 13c4 for the rest, so 10 x 715 = 7,150.
2 repeated numbers: 10c2 ways for determining which two numbers are repeated, multiplied by 12c2 for the rest, giving 45 x 66 = 2,970.
Finally, for 3 repeated numbers, there are simply 10c3 possibilities, which equals 120.
Adding up all of these numbers again gives 13,243 and multiply by 899 and you have 11,905,457.

Re: How many Numbers puzzles are there in total?
Can we now have a breakdown of those 11,905,457 games please?
I'd like to know how many games are possible to solve, how many 1 away is the best, 2 away, and so on.
Would probably be neat to split this out by selection type as well.
Thanks in advance, will check back in ten minutes.
Actually, I'd also be interested to see it split out by target. So some kind of threedimensional reporting cube please. 15 minutes.

I'm actually going to do this ^ myself. I'll publish my results. Then numbers games can be reduced to a simple memory exercise. Ocelots seem nice despite shin camera, and all that.

Didn't William TungstenPaedo do it?

I was also wondering how we find out how many of those games are possible or not. Good chart there posted!!
I also wonder how RR figures out whether a Numbers game is impossible, or does she just get told that?

That's interesting. I was wondering if she got told whether it was possible after watching an episode this week where she said she got three away when the nearest possible was two away.

I know CV had the numbers written down on her clipboard for her so she doesn't waste 10 seconds of the time writing them down, I assume RR does too.

From RRs reactions to the crew sometimes it looks like she is probably told easy ones are possible sometimes!
Re: How many Numbers puzzles are there in total?
My hunch is that she isn't told until after the 30 seconds. My thought process changes a lot if I have the luxury of aiming solely for the target rather than trying to get as nearaspossible (and she'll often say that she was n away).Philip Wilson wrote:From RRs reactions to the crew sometimes it looks like she is probably told easy ones are possible sometimes!

Re: How many Numbers puzzles are there in total?
Don't worry Tom, I'm already on it. My estimated completion time is well under yours though (about a month running on my desktop!) I'm producing a csv file of basically every numbers game so I can slice it all up at will. My solver program can take parameters (e.g. produce the csv for games 10,000,000  11,905,457) so I might share out the CPU work if there are some volunteers...Thomas Carey wrote:I've modified my crappy numbers solver to work this out.

Re: How many Numbers puzzles are there in total?
I made a (what turned out to be huge) optimization to my procedure and it's now finished. Yes, I have a list of all 11,905,457 numbers games, and whether they're possible or not (and if not, how close you can get). My optimization was actually simply to ignore the method itself  I was writing out a 'method' for each game, which I decided was pointless since there's nothing really you can sensibly do with them as a set. If you want a method for a particular game you can bung it through a solver in a second. (The reason that this sped it up so much was because solutions have to be optimized  my program bruteforced EVERY combination of operations with the numbers. In order to get a sensible method, you find the one with the fewest steps, otherwise it might go 25*5 = 125, 3+4 = 7, 100+6 = 106 to solve the puzzle with a target of 106. Obviously the first few steps are garbage, but the solver doesn't know that without adding expensive overheads. If we don't care what the method is, we can drop out as soon as we hit any method that gets the right solution. Since most games are possible to solve exactly, this makes a huge saving.Jon Corby wrote:Don't worry Tom, I'm already on it. My estimated completion time is well under yours though (about a month running on my desktop!) I'm producing a csv file of basically every numbers game so I can slice it all up at will. My solver program can take parameters (e.g. produce the csv for games 10,000,000  11,905,457) so I might share out the CPU work if there are some volunteers...
So, maybe I should just turn the file over to Graeme so he can start answering questions. Or maybe I'd like a little play around with it first.
Any specific questions once we get past the ones posed above? Do you think, for example, there is a selection of numbers for which you can always get 10 points, regardless of the target?

614 of these are 1 large selections.
603 are 2 large.
4 are 3 large.
5 are 6 small.

What about the same question the other way round... which targets are solvable by every 1large selection? Every 2 large? 3 large? 4 large?
Which target is solvable by the fewest selections?

Re: How many Numbers puzzles are there in total?
I'll guess 911 or 937 for the least solvable target. High primes, and good distance from multiples of 25 (I don't think the 937.5 trick will add that many for the second).Graeme Cole wrote:What about the same question the other way round... which targets are solvable by every 1large selection?

Haha no, but I once asked one of my friends (sadly dead now I'm afraid) to do something similar and have finally dug out the results from an ancient hard drive. Incidentally he only made it 10,871,986 possible games, so it's possible he missed some or did something wrong somewhere (I've only got the text output, rather than the code, so I can't really tell).Jon Corby wrote:Fuck you Jim, don't you be stealing my thunder now!

947, but even then there 9,017 selections which solve and only 4,226 which do not.Graeme Cole wrote:Which target is solvable by the fewest selections?
It's then small steps to the next worst, 941 (9045 solve, 4,198 don't), and similarly onto 967, 933 and 937 (TCap's other guess of 911 is #23 in the list.)
The first 'baddun' that isn't in the 900s is 853 at rank #13 (9453 solve, 3790 don't)

Re: How many Numbers puzzles are there in total?
It's the difference between a random 6 small numbers game (you) and sampling random 6 small numbers selections (apterous/solver). The unsolvable games are more likely to have a lower probability of appearing under apterous/solver due to being more likely to feature repeated numbers. Same for x large.Jon Corby wrote:Interestingly, the percentage solvable on that Solver FAQ are less accurate than I would have expected. I wonder how big their sample size was?

Ah yes Matthew, of course, you're absolutely right. I'm talking purely about the pool of possible distinct games, ignoring that in reality some of those are much rarer than others. Thanks, that makes perfect sense.

Let's consider how likely that would be; (a) I didn't know David Bowie and (b) if I did I would imagine he had better things to do than write Countdown numbers game solvers for me, so (c) I wouldn't ask him to.Gavin Chipper wrote:Was it David Bowie?JimBentley wrote:Haha no, but I once asked one of my friends (sadly dead now I'm afraid)
