@QPaysTaxes Wow, I'm really interested in a better solution now

You could alpha/beta with variable depth. Full tree would give perfect play, etc.

@JesterTran Practically anything that can be done in one programming language can be done in any other programming language. C is no exception.

@HelkaHomba Man, I'd love to see object-oriented programming in Befunge :D

@QPaysTaxes Right, haha

Where is the best place to start off with basic AI?

@QPaysTaxes Goodbye, thanks for the input and I'll check wiki! :D

Geobits

@JesterTran Usually at home in my experience. That way if it goes rogue it's locally contained and won't get to Skynet phase.

Jester Tran

@Geobits I mean how should I start off learning AI? What concepts or websites do you recommend?

Dennis

Never watched it.

it's fantastic and everyone should read it

Sherlock9

Usually the series of novels, but also the radio plays

Dennis

Ah, that's the thing 42 is from, right?

Yep

Geobits

@JesterTran I know. It was a joke, but I don't have any specific recommendations. There are so many sites with basic intros to google up that it's hard to choose one.

Jester Tran

Night!

@Geobits lol, I had a feeling it was a joke..

Doorknob

Now the world has gone to bed,
Darkness won't engulf my head,
I can see by infrared,
How I hate the night.

Now I lay me down to sleep,
Try to count electric sheep,
Sweet dream wishes you can keep,
How I hate the night.

@QPaysTaxes night! :P

Geobits

@JesterTran But also serious. We don't need Skynet happening ;)

Helka Homba

@Dennis The story is fairly random, a bit like Alice in Wonderland. Maybe it's above my head but I never really appreciated the book.

Geobits

"fairly" random is putting it lightly.

Doorknob

5:12 AM

It's a very... particular kind of humor

Geobits

It's decent enough, but not as good as the hype would have you believe.

Much like any cult classic, I guess.

Sherlock9

I prefer Terry Pratchett's Discworld series

Doorknob

@Geobits respectfully disagrees :P

Geobits

@Doorknob You also like nethack, so I suspected we'd disagree on this as well :P

Doorknob

@Sherlock9 I've read the first few of those too! They're amazing, and I've been wanting to continue the series for a while now, but I haven't gotten them yet

Geobits

5:14 AM

I'm reading 11/22/63 atm (as in kindle in hand).

Doorknob

Took me too long to figure out that was the name of a book...

Sherlock9

@Doorknob I have read the first dozen or so, but it's been so long that I may reread a few

Geobits

@Doorknob Oh, sorry. It's the name of a book.

Doorknob

@Geobits thanks

To try to keep the spirit of the Three Word Chat room, I'm going to post a full explanation of the rules here and link it there (since most of the users are going to come from here anyway).
1. Three words per message. This include pings, links, and anything else. Words are delimited by spaces.
2. Please don't do things that go against the spirit of three word chatting. This includes using non-space characters to separate stuff that would normally be separated by spaces. That's loophole abuse, and kinda ruins the point of the room.

then idk how to do that, because H, T, H, T (etc) H, H, H and H, H, T, H, H, T, (etc) H, H, H are both valid as well then

Mars Ultor

C# uses \referenceEquals for that IIRC

Depends which one is used more often

From an OOP-based standpoint, is/instanceof is used fairly often, directly proportional to how OOP your code is

Kenny Lau

@Katenkyo How would you golf i-1>0?

Although if you intend for this to be a fast-to-code language, OOP is probably not very important

@KennyLau I'm glad I've been useful!

oh, 2D array cannot have a[0][3]

@KennyLau It could, in languages where indexes are 0-based, like VB.NET.

Kenny Lau

8:13 AM

@mınxomaτ Lua is 1-based

Katenkyo

@KennyLau not really, 1-indexed, but it prevent the case when my "cursor" is on the border of the array, and I'm checking for the surrounding chars

Kenny Lau

@Katenkyo nil ~= s is true anyway

@Katenkyo a[3][0] is just nil where a[0][3] is error

why not?

@KennyLau `oh, yeah, didn't see, but in this case it will always stay at 2

Kenny Lau

how are they different?

@Katenkyo Useful result: -1%3 == 2 returns true

Katenkyo

the problem here is that t increment when i==t, but if i increment when it is lesser than t, we have to change them at the same moment else we have two possibilities:

either i and t will increment at each turn (i never returning to 1)

either t and i will always be 1

Kenny Lau

i always think that block can be reduced much further

Katenkyo

@KennyLau it may be possible, but by totally refactoring it, not just suppressing checks I think

Kenny Lau

8:24 AM

i'm thinking

by the way, #m can be shorthanded for the moment

Katenkyo

I suppressed r, it works, I'll update the post soon

@KennyLau may not be possible for #m as it is used only 3 times

yeah, it would ccost be 1 byte to put it in a variable, not enough calls ^^
