ARC-AGI-2 problem / Optimize by Ciro Santilli 37 Updated +Created
There is no unique solution, we just have to optimize something, often the least changed colors.

ARC-AGI-2 problem / Object by Ciro Santilli 37 Updated +Created
An "object" is a set of points that is understood to be one singular entity.
Contiguity and having the same color are strong indicators that something should be understood as an object.
ARC-AGI-2 problem / Background color by Ciro Santilli 37 Updated +Created
If a color is inferred to be a background color, it contains no information and should be ignored.
Most problems tend to use black as a background color, but not all of them.

Bitcoin 2011 vanity address pool by Ciro Santilli 37 Updated +Created
This section lists transactions from 2011 that appear to contain pools of vanity addresses. There were first discovered while researching Base58 messages, but since they just contain bulk commercial stuff with little artistic value we've decided to keep them here instead of in the museum:

Solution: vs are guns that shoot diagonal line of their color, when line touches another object, change line color to match that of the object, then bounce on the object and continue going with the new color
Input primitives:
Assumptions:
  • line don't cross each other, it is unclear how to resolve that case
Transformation primitives:
  • draw line
    • draw line and bounce
ARC-AGI-2 problem / List / 16b78196 by Ciro Santilli 37 Updated +Created
Solution: move pieces to fill the gap on the fat object that crosses the screen. Place objects either on fat object or on other objects placed on the fat object. Anything you add must end in a rectangle.
The rules for this one are not entirely clear with the number of examples.
Also clearly if the goal is to make rectangular towers, then this is an NP-hard optimization problem in general.
Input primitives:
  • same color chunk. Properties: crosses screen.
Transformation primitives:
  • move solid around
  • fills the gap

To the left of the vertical red line, count the number of each color on each row.
Then to the right, on each line draw one square of each color to the left every n columns, starting with a square on the first column to the right of the red line, where n is the count of that color.
Start with the color furthest away from the red line, and then color with colors nearer to the red line. If there's overlap, replace the old color with the new one.

ARC-AGI-2 problem / Primitive by Ciro Santilli 37 Updated +Created
These section lists common visual primitives that a solver must first extract in order to infer solutions.
Some of these have a lot of prior world content, others less.
Many people have come up with the same idea on the Discord. Some nicely call it DSL.
