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

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...

Q: Mask an IP address and give its broadcast

Digital TraumaBackground Inspired by this Unix.SE question (and of course my own answer). When an IP address is specified for an interface, it is often given in this dotted-decimal form: a.b.c.d e.f.g.h where a.b.c.d is the actual address and e.f.g.h is the netmask. The netmask, when represented in binar...

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

Granted, Ken Iverson made both APL and J. So the model train enthusiast theory is still plausible.

@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.

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
 
Dennis
Dennis
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

are they like dataflow specifiers, lazily building functions which are eventually applied to the arguments?

They're like a school of goldfish, gently adrift in a sea of nightmares.

I'm not sure what a dataflow specifier is, but building functions which are eventually applied to the arguments sounds about right.

Well, I learned Ruby some time ago, but there's large chunks that I forgot since I don't use Ruby very often
And I'm not currently learning any languages. At least, not actively. I'm taking a break from that
As for languages I know... A bunch of Python 3, some Python 2, some Ruby, a little Golfscript, a little Pyth, a little CJam, and some C and C++

Q: Why isn't there default code formatting like on Stack Overflow?

JojodmoI was going through Code Golf, and I noticed that there is no default Google code prettify like there is on Stack Overflow. Is there any particular reason for this? I recently updated one of my submissions to be syntax highlighted. I think we can all agree it looks much nicer than the non-highli...

@CᴏɴᴏʀO'Bʀɪᴇɴ my bot beat engineer-bot ;P
 
El'endia Starman
El'endia Starman
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
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
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
 
El'endia Starman
El'endia Starman
I'm quite sure of that.
It's hard to pull off.
You could probably do something with quadrants.
Or just compute all four cross-boundary virtual positions of the enemy.

I'm going more of "is facing the guy normally or facing directly away have a shorter delta_angle"
and for dist calc, dist<100 || dist>900 :)

@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
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

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

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

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

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.

But if you'd type 45 or so, you'd expect the bots to somehow circle around the sun, don't you?
 
Sherlock9
Sherlock9
@flawr I think that should be 90 degrees for orbiting
 
El'endia Starman
El'endia Starman
No, what I'm seeing is that 45 degrees is functionally the same as 0 degrees.
 
flawr
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
El'endia Starman
10:33 AM
oh wait
-180 <= angDiff <= 180
What you really want to change is this line: 
var ang1 = gameInfo[botVars["color"]+"_rot"]+90
 
flawr
flawr
This reads the angle of the bot, relative to the coordinate system, right?
 
El'endia Starman
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
flawr
If gameInfo[botVars["color"]+"_rot"] == 0, then the ship is pointing in positive x-direction, i assume?
 
El'endia Starman
El'endia Starman
No, actually, it's pointing in the positive y-direction. I think.
