ARC-AGI-2 problem / List / 16b78196 Created 2025-03-28 Updated 2025-07-16

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.

Input:

Output:

draw dotted lines

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.
