@Doorknob冰 because you can have linear chains. a complete binary tree has each node filled before attaching children to them

Alex A.

@LegionMammal978 Nice try :P

Dennis

@LegionMammal978 I'd say nice try, but people will star it eventually.

Doorknob 冰

@quintopia no it doesn't

Binary tree

In computer science, a binary tree is a tree data structure in which each node has at most two children, which are referred to as the left child and the right child. A recursive definition using just set theory notions is that a (non-empty) binary tree is a triple (L, S, R), where L and R are binary trees or the empty set and S is a singleton set. Some authors allow the binary tree to be the empty set as well. From a graph theory perspective, binary (and K-ary) trees as defined here are actually arborescences. A binary tree may thus be also called a bifurcating arborescence—a term which actually...

@Dennis Hi

Doorknob 冰

Or do you mean, you can have chains of multiple 1-node thingies in a row?

quartata

@Dennis Well that's just downright weird.

how about other sequences that return themselves after TWO applications of RLE?

quartata

That... is also the version I'm running.

Oh you know what

Dennis

@quartata Do you have a permalink that should be working?

quartata

Yeah one second

pl.tryitonline.net/…

I think I know the problem though.

any and all are part of List::Util 1.33 which might not come by default with all perl versions

Dennis

Looks like that's the case.

quartata

00:10

Yep that's it.

Since product is part of 1.35

I'm not sure why my version of Perl has those when yours does not

quintopia

@LegionMammal978 why j00 looking at ALPACA

quartata

At any rate you should be able to install the latest via CPAN

cpan List::Util

Dennis

@quartata Perl and its modules are provided by different packages.

@quartata That doesn't work for me. The VPS seems to be lacking the required RAM to build CPAN...

quartata

@Dennis List::Util comes with Perl by default as of some version.

The question is which version of it comes

@Dennis :/

Hrmph.

I can remove the any all product stuff and replace them with appropriate reduce calls

One second

LegionMammal978

@quintopia What about ALPACA?

Dennis

00:21

@quartata I found any and all in List::MoreUtils. No such luck with product though.

@Dennis Don't bother I'll edit pl to not need them

I was naming my variable sun

I guess sn works just as well...

El'endia Starman

Should I put a list of variable/function names not to use in the question?

quartata

@Maltysen I saw you lurking around in the pl chatroom earlier

Maltysen

the OP says not to access or alter any of the global vars, but can I just for convenience?

quartata

What do you think its chances against Pyth are?

Maltysen

like instead of writing a full polygon intersection function, using the point arrays

El'endia Starman

@Maltysen Well, I could add sun to the list of vars you can access.

Maltysen

03:03

and both ships?

El'endia Starman

I'm also considering making the collision checking functions accessible.

Well, I want to avoid any possibility of cheating.

If I let you use window["red"] (which you technically can access), you may accidentally or deliberately change one of its variables.

Maltysen

I mean, you can include copies

El'endia Starman

hmm

Yeah, I think I could do something like that.

Well, tack is just the name of the character. The rest is actually J syntax, I think.

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ I think your bot actually revealed a bug. It's possible for a ship to be hit in the same frame that the command to go to hyperspace is given, so sometimes the ship disappears and then fragments appear.

Also, I've pitted Engineer against Engineer three times now, and every time, Blue has won by a significant margin. Interesting.

4/4 now.

Alex A.

10/10

El'endia Starman

Can someone else try Engineer vs Engineer here and see if they also get Blue beating Red by a margin of ~50% fairly consistently?

Hmm. Red often fails to hyperspace when in danger of hitting the sun, and when Blue hyperspaces because of the sun, so does Red...

@Dennis I do not understand APL, J, or Jelly. I lack a mental (physical, intuitionistic) model of this computation model

It takes a little time to get used to it. I believe Jelly should be easier to learn that J/APL, since it does not overload operators with a monadic and a dyadic function.

can you not provide a metaphor that would make it make sense, or explain what it has in common with some other language i do understand

I have actually seen multiple missile strikes on Engineer bots. They all happen when the firing ship is really close, so the missile crosses the distance in an instant.

Maltysen

My bot also used hyperspace, so it was more of a who can trigger more hyperspaces and get that 25% battle

El'endia Starman

haha, yeah

I think the most successful bot probably will use hyperspace, because it's a maybe death versus a certain death.

Maltysen

I'm gonna try and make my bot aware of the field being a toroid

it seems like it would help a lot

I'm quite sure of that.

@El'endiaStarman whoa unrelated to the toroid (in fact this technique is failing only because of the toroid), I got a really good sun avoidance technique

If outside some "danger" radius where it flies straight out, it tries to fly perpendicular to the sun

El'endia Starman

very cool

Have you checked out OrbitBot? It's surprisingly good at getting into a nice circular orbit.

I saw one round where it was OrbitBot against...Engineer, I think, where the Engineer bot destroyed both wings of OrbitBot's bot, but because it was already in orbit, it just waited out the Engineer bot... :P

Yes, it’s called the prompt

Anyone here code Nim?

Sherlock9

I don't but I could learn. Got a link to either the esolangs wiki page or a tutorial?

@El'endiaStarman Can I reuse some code from codegolf.stackexchange.com/a/67563/24877 ?

I like the simlicity of your code but I'd like to make some changes/add some features=)

El'endia Starman

@flawr Sure, go ahead. :)

flawr

Thx=)

I think one big improvement could be made by making the firing rate also dependent on the velocity.

El'endia Starman

10:20

...how so?

Also, 10 bots have already posted, so it's a bit late for that. Unless you mean the bots' behavior...

flawr

Well I just thought if you are close to the sun, but the velocity in direction of the sun is zero, there is no need for firing.

El'endia Starman

ahhh, gotcha

I thought you meant missiles.

Hello everyone!

flawr

Oh sorry for the confusion=)

Hi @isaacg

El'endia Starman

hullo!

Well, I'm off to bed.

goodnight

El'endia Starman

But before I go, a present: Radians and Degrees D3 applet. Merry Christmas everyone! :)

flawr

@El'endiaStarman Do you know GeoGebra?

El'endia Starman

I've used it a few times.

flawr

PS: I tried to change the behaviour of your bot by setting the critical angle to something other than 0

But nothing really changed=)

El'endia Starman

What about 180?

flawr

10:29

Then we get suicide bots

=)

El'endia Starman

haha, yup

flawr

But if you'd type 45 or so, you'd expect the bots to somehow circle around the sun, don't you?

Sherlock9

@flawr I think that should be 90 degrees for orbiting

El'endia Starman

No, what I'm seeing is that 45 degrees is functionally the same as 0 degrees.

flawr

I think that is strange isn't it? I mean that should result in a 45° angle between the line to the sun, and the direction the nose is pointing.

El'endia Starman

10:33

oh wait

-180 <= angDiff <= 180

What you really want to change is this line:

var ang1 = gameInfo[botVars["color"]+"_rot"]+90

flawr

This reads the angle of the bot, relative to the coordinate system, right?

El'endia Starman

basically, yeah

You can either do that or add another line:

angDiff = (angDiff + 90)%360

actually, no

var angDiff = ang2 - ang1 + 90;

flawr

If gameInfo[botVars["color"]+"_rot"] == 0, then the ship is pointing in positive x-direction, i assume?

El'endia Starman

No, actually, it's pointing in the positive y-direction. I think.

It's 5:40 AM here. I'm going to bed. [Obi-Wan voice] Use the console, flawr.

flawr

Ok, thanks=)

Good night=)

So I posted an answer to the quipu question a few hours ago, and it turns out that question a little more work than I thought it would be. Have a look. codegolf.stackexchange.com/questions/67603/…

Optimizer

quipu is a real name?

Adnan

Does anyone know how much bytes this is?

0

A: Is my name official?

grep ~11-~23 chars (I'm new - how do switches count?) This is the pattern: [A-Z][a-z]+ If you use the -E and -x and -c switches grep will print a count of matching input lines. So if you give it one line you get a 1 or a 0. I think that's how this place works. The pattern is 11 chars, the w...

I'm not familiar with this

@Adnan I'd count it as 13 (11 bytes code + 2 bytes of flags: c, x), following these guidelines

Sherlock9

@Optimizer A quipu is an Incan invention. It's how the Incans kept records of numbers and, with some supplemental symbols, words

My dang answer saved before I finished typing it ಠ_ಠ
