Re: Spoilers for Wednesday 10 February 2016 (Series 74 Prelim 13)
ENMASKED is listed as valid on Apterous. Sigh. It is valid indeed. ENMASK an alternative spelling of INMASK, but the search bar doesn't find ENMASKED. Susie should always check the non-inflected word. I don't understand this at all - if you've spent even a little bit of time on the ODO since its ma...

Re: How many Numbers puzzles are there in total?
Which ones give the best average solvability across all sets of 4 (so for example 12 has 88.28% with 16, 18, 24, 91.76% with 37, 62, 87, etc. and then taking the average of these)? Was what I was originally thinking, though you've answered an equally interesting question anyway. In that case, your ...

Re: How many Numbers puzzles are there in total?
Which large numbers are generally most useful, across all combinations with other numbers, and which are least useful? 97 and 12 respectively? Nope. The most useful numbers, in order (some omissions) are: 11, 13, 12, 14, 17, ... , 92, 90, 98, 96, 100 97 comes in 15th from bottom. As you can see, 12...

Re: How many Numbers puzzles are there in total?
By the way, if you're only playing 4L, the best possible set of large numbers is 12, 14, 17, 57, with 49,438 / 49,445 (99.99%) of games solvable - only 7 games not solvable! The unsolvable games are: 12, 14, 17, 57, 1, 1 ---> 344 12, 14, 17, 57, 1, 1 ---> 381 12, 14, 17, 57, 1, 1 ---> 423 12, 14, 17...

Re: How many Numbers puzzles are there in total?
Where do 12, 37, 62, 87 fall? 2 prime numbers, and 62 having 31 (a prime greater than 10) as a factor should put it much higher than the default. 87 = 3*29, but anyway... 12, 37, 62, 87 comes 1,810,325th out of 2,555,190 (30th percentile, so worse than 97, 98, 99, 100) with a breakdown as follows: ...

Re: How many Numbers puzzles are there in total?
Great topic, enjoyed reading all this! Harder question: if one were designing a new variant, which four large numbers (in the range 11-100) make the game hardest (i.e. fewest games solvable) and which easiest (i.e. most games solvable)? I have an answer for you, Charlie. The easiest four numbers ar...

Charlie's question was about using different sets of large numbers - and 100*99*98*97*10*10 is way too big, for example.Ian Volante wrote:Really?

Just an update on Charlie's question - I've got full statistics for how many 0,1,2 or 3 large games are gettable with each possible set of large numbers. I was expecting to be completely done on the 4L by now as well, but my program hit a snag after I kicked it off and I didn't notice until now. For...

I'm okay with an imperfect answer, I'm sure we can get somewhere with a bit of stochastic hill climbing or some such.

Re: CoC Quarter-Final 1 Spoilers For Thursday January 14th 2016
Excellent, dramatic game, although I'm unclear on the rationale behind going for 2 large in the final numbers game. If you're "relying on the conundrum" anyway, why not try for a trickier numbers game - then, even if you don't get it and your opponent does, you can "rely on the conun...

Re: How many Numbers puzzles are there in total?
Jon, how long does your program take to solve all the numbers games? I've dug up my old code (and made a couple of tweaks) and it can chow through all the standard numbers games, including recording an optimal* solution to each one, in a matter of minutes. That's mightily impressive - is there any ...

Re: How many Numbers puzzles are there in total?
Yep, that agrees with the rough memory I had from ~2 years ago when I did this myself. I don't remember 2 or 4 large being quite so similar to 3 large in terms of gettable targets, but my overall surprise at Nasty 3 large being THE most gettable numbers variant probably just dulled my memory of the ...

Re: How many Numbers puzzles are there in total?
Jon, I think you should do a similar analysis on the solvability of numbers games with the "nasty" large numbers as used in a couple of special episodes (those larges are 12, 37, 62, 87). I've done that analysis in the past and there's something very obviously surprising about the results ...
