PokerChipRace multiplayer challenge discussion

What would you call “dead droplets” if it’s not the neutral droplets ?

The droplets that have bean eaten and that are no longer in the game.

Every time a chip accelerates, the chip will expel a fifteenth (1/15) of its surface area and will shrink in diameter.

tick 1: entity 1: radius 25.0
tick 2: entity 1: radius 24.152295

24.152295 / 25 doesn’t look like 1/15

1/15 of the mass.
Mass is proportional to the radius squared.
You’re missing a square root somewhere :slightly_smiling:

to improve performance, no need to calculate a square root for each chip : new radius = current radius * 0.96609178

where 0.96609178 = sqr(14/15)

Yay! I’ve just been promoted to bronze. I’m so happy I had to share! :joy:

I haven’t submitted any code since last year. (here’s the date for reference)

That code was actually my first submission. (here’s my submission history. Dates not a year ago are the league system autoresubmitting my stuff)

And I made it to bronze already!!!

I’m not going to add a screenshot of my code. That would be cheating. Probably. Or against the rules in some way. They always find a way to bend the rules to make it against them.

I’m only going to paste my first line, that’s not really code, it’s a simple comment.

Yup. I’m in bronze with the default code (and a custom comment.) Go me! and thanks CG!!!


I fixed one small global variable bug in my game simulation code and jumped two leagues. That was a pretty great feeling.

Note to self, don’t use global variables that aren’t actually global!

hey,would you tell me how to set the seed info into the “test” manually??

On the left: SETTINGS -> mode:EXPERT
then you have two tabs below your code: players and options. Go to options/manual and copy-paste that text.

However, the droplets are smaller than my own chip for that seed.

I just started this multi. My original intention was to write a very simple heuristics to get out of Wood 2. I made a bug, resulting I accidentaly always sent WAIT. To my amusement this bot overtook cca 1000 players, ending in middle of the full leaderboard (still in Wood 2 though).

Then I corrected the small bug and the bot started to play as intended - thus dropping by 200 places… :slight_smile:

PokerChipRace has a big design flaw. It’s very difficult to achieve a “good” move. “good” as in “good enough to not destroy yourself”. Hypersonic got the same design flaw (but in a less harmful way).

It’s an old puzzle so there’s no way CG will change it anyway.

But it’s a good “anti-example” for puzzles creators :smiley:
