Min-Max is a box that is capable of determining which of the two numbers is the higher (Max) and which is lower (Min). I need to use minimum amount of boxes in order to sort 4 different numbers (any A, B, C, D). For example:

12:57 AM
(Apologies for the slow response.) @North, the wording is not the same in #1, #2 and #3. For instance, #1 says "In the following position, is it possible that White could still castle?" whereas #3 asks (in the question itself as well as the title) just "Can White castle?".
@JohnDvorak, the point isn't to make any of them easier, it's to make the question actually being asked the same as the one being answered. E.g., #2 (unlike #1, like #3) just asks "Can White castle?" and the accepted answer says yes and shows a game leading to the given position followed by W castling. But, strictly, that isn't the right answer to the question, because there are other ways to reach that position and after some of them W can't castle.
Of course this is all rather pedantic; there's no real doubt what question is actually being asked. But it's so easy to actually ask the right question and it's a shame that in #2 and #3 that isn't what's happened.

Ah. Multiple histories.

(Sorry, "actually" is being used in two opposite senses in that sentence! I hope the meaning is clear anyway.)

Pedantic indeed :P

I'm a mathematician, which is to say a professional pedant. And I spent a substantial chunk of my day reading a patent draft, so maybe I'm just in that sort of mood.

Trust me when I call something pedantic, it's a pretty strong damnation :P

i think the convention in chess puzzles in general is that castling is possible unless shown impossible
unlike with en passant, where you have to prove that the opponent's last move was one that makes en passant possible
that said, nothing wrong with making it extra clear like shoopi did in the first one

is it fair to use "nth [word]" to mean the nth letter of the word
e.g. "first mate" to clue M
or does it need to be "mate's first" or "first of mate" etc. where the grammatical relation is made clear

7:36 AM
I prefer a possession indicator here, so "[word]'s nth" or "nth of [word]", but I've seen "nth [word]" quite often. I think this construction is used more often by Americans, but that's just an observation.
(There is, of course, always the case where not using a possessive improves the surface reading as in your "first mate" example.)

7:48 AM
or maybe first in mates?

yeah, another thing is that using the possessive can make it a bit too obvious
i mean, even if "mate's first" works for the surface there aren't many other things that can refer to
whereas with "first mate" it isn't immediately clear - maybe we need a synonym for the nautical position? maybe it's EVE (as in "first romantic partner")? maybe the "first" refers to the preceding word instead?
but then again i've tried using the construction without the possessive in a clue, and someone was confused about the clue even after seeing the solution... which is not what you want

Case in point is the current C4, where "ruined tail" is D, which I only saw after you commented on it yesterday.

\$Given\$: \$A\$, \$B\$, \$C\$, \$E\$, \$F\$ are distinct digits varying from \$1\$ to \$9\$. \$A\$ is a Fibonacci number. \$BB\$, \$BC\$, \$EF\$ are concatenated Numbers. \$Relationship\$: \$(A*BB)*(BC^2)\$ = \$(EF^2) - B\$ Deduce all the Digits.

wow, Uvc's seriously making a killing on the hot network questions front
45 HNQ entries in 54 days

do you have a query for that? @jafe

just the one Uhoh posted a while back
he has 62 currently, i have 58... uvc's overtaking us both any week now

wow...

(also consider that the data goes back 5 months, but uvc has only been posting for less than 2)
so yeah pretty impressive

11:05 AM
@OmegaKrypton Nope. Sadly no progress since my last status report. Been a busy few weeks for me... :/

11:37 AM
Keep it up! @Alconja

Thanks for the support. :)

Simple R Script to brute force it: require(gtools) #Generates permutations data<-as.data.frame(permutations(9,5,1:9)) #Makes A fibonacci numbers data<-data[!(data\$V1==4|data\$V1==6|data\$V1==8),] #Calculates LHS and RHS data\$LHS<-data\$V1*as.numeric(paste(as.character(data\$V2),as.character(data...

this showed up in my low-q answer queue.
i deleted it as not an answer due to the no-computers tag in the question. this is a brute-force approach that does not comply to the logical-deduction requested by the op
is this the right way to deal with this?
thanks!

Can you find why does the below relation hold true?

IA creates lots of debates about potential problems such as overtaking humans or destroying jobs. I'm not sure about AI but since 1985 Terminator, I know that two IA ("Intelligence Artificielle) surely creates a problem : I A + I A ----- P B But can someone explain why ^^ ?

The theater group began today with a warming up game. Everyone has been assigned a role and is now either a bad guy who always lies, or a good guy who always tells the truth. Max, who comes late, is asked to explore the roles of Jan and Jörg through yes-no questions. "Are you both good guys...

Here's a miniature selfmate puzzle that I composed today. I just got an idea and I managed to successfully create it. I got the basic idea down to just 9 pieces, none of which are promoted. It's White to move and force Black to checkmate them in 10 moves. Naturally, Black tries to prolong their ...

An idle thought that never made it to a puzzle:
What have these byway names in common?
First Street, Doctor Drive, Count Court.
If you have another example, please allow.
(Yes, they are real street signs in my whereabouts. That's not the only thing they have in common.)
(Another goodie around here, so-called Silicon Valley, is Disk Drive.)
(And East North Street.)

Yeaman Shore!

Lots of pieces are tangled here. Can you find mate in one?

@Adam , if that's an addition to my list, i'm truly puzzled.

@humn Nah its a joke

I already giggled from recogniszing the rhythm. Care to expand?
Might be a cultural gap, which i love! Signed, not even a native speaker of the language, English, which i love to a fault.

i think what they have in common is their abbreviation?
1st st, dr dr, ct ct?

7:34 PM
@jafe : Uh-huh! Any other examples? My brains are wracked.

! (now i have to wipe off my keyboard)

not sure if one exists but sounds like it shoud :P

One that almost made the list is State Street, another around here.

Apparently Plank Place exists

7:41 PM
@Adam , !!! Gotta appreciate the ambiguous spelling.
Gotta hand it to you, @Jafe, you bypassed 2nd.
How about Hello Avenue? In Latin.
(>! Ave Ave.)

heheheheheheheheheeee
Oyoyoyoyoy!

this should have been one of the first ones... Saint Street

Best yet!!!!

that one rolls off of the tongue

I was banned, once, for rallying for a puzzled workshop. Then this place.

don't worry, the mods are asleep

no we aren't

yikes!

Sleep? What's that?

@Deusovi , please get some sleep. If not, did you solve my cross(boundaries)words?
@Mithrandir , sleep = what most do at night, except here.

7:54 PM
@humn Wait...you don't replace your batteries?

(I've been on the night shift so long that my 60-yr-old skin has no wrinkles.)

I'm getting enough sleep, don't worry! And I haven't really taken a look at them yet -- I was planning to wait for the finished puzzle (though I could try out the examples now)

@Deusovi, you have many more important things to do. And i appreciate your notice. What you saw are my dipping yet another toe into the world of crosswords,
a world that fosters my closest relatives.
Only two of whom are native English speakers. All of whom appreciate the USA/wherever-else version.

Is PE down atm?

All of SE is currently experiencing an issue, looks like.

Just as I said that it came back palm to face

Seems back now.

My computers have been taking some hits lately. Foul play is afoot.
As if that's anything new.
When it gets serious i go beyond puzzle solving. Into problem solving.
My line, which is often enough enough: "You don't want me against you."
I want to amuse! To intrigue! To anything else but thwart.
Likewise, please amuse and intrigue me at no judgement

Matthew woke up suddenly. He was in a dimly lit room -looked like an old office space. He stood up in a panic and looked around. He saw a few desks, ancient computers, yet no dust anywhere. He made a full turn and then saw a door with an exit sign above it. Matthew tried to open the door, but it ...
