arcsolver 0.0.2

A Python library for automatically solving Abstraction and Reasoning Corpus (ARC) challenges using Claude and object-centric modeling.

arcsolver

This library contains tools for visualizing, analyzing and solving tasks from the Abstraction and Reasoning Corpus (ARC) challenge dataset.

Interaction with Claude

Installation

Install latest from the GitHub repository:

$ pip install git+https://github.com/agemoai/arcsolver.git

or from pypi

$ pip install arcsolver

Key Features

• Task Management: Load and visualize ARC tasks with the ArcTask class
• Object-Centric Modelling: A set of primitive classes for representing grid objects and transformations
• LLM Integration: Designed to use Claude Sonnet 3.5 for automated task analysis and solution generation
• Extensible Architecture: Easy to add new primitives and helper functions to enhance solving capabilities

Quick Start

Task Representation

The task module provides classes for working with ARC tasks

from arcsolver.task import ArcGrid, ArcPair, ArcTask

task = ArcTask('1e0a9b12'); task.plot()

An ArcTask comprises a list of input-output example ArcPairs, each of which holds two ArcGrids. Each class has convenient plot methods for visualization or directly outputting to base64-encoded strings that can be passed to Claude

print(f"Input grid 1 plot: {task.train[0].input.plot(to_base64=True)[:20]}...")

Input grid 1 plot: b'\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR\x00\x00\x01H'...

Object-centric Models

The ocm module provides a set of primitive classes for constructing object-centric models of ARC grids

from arcsolver.ocm import Vector, Rectangle, Line, Grid, Color, Direction

grid = Grid(
    size=Vector(8,8),
    background_color=Color('grey'),
    objects=[
        Rectangle(position=Vector(1,1), size=Vector(2,2), color=Color('red')),
        Line(position=Vector(6,1), direction=Direction.NE, length=6, color=Color('pink'))
    ]
)
ArcGrid(grid.to_array()).plot()

Task Descriptions

Use Claude to analyze and describe ARC tasks

model = 'claude-3-5-sonnet-20241022-v2:0'

from arcsolver.describe import DescriptionGenerator

describer = DescriptionGenerator(model, client_type='bedrock')
d = await describer.describe_task(task, 1); print(d[0].d)

The input grids contain various colored squares arranged in different patterns against a black background. The transformation applies a "gravity" effect where all colored squares fall to the bottom row while maintaining their relative left-to-right ordering. Vertical sequences of the same color in the same column compress into a single square in the bottom row. All rows above the bottom row become black except where vertical sequences of the same color maintain connectivity.

Solution Generation

Use Claude to construct a solution to an ARC task, automatically refining its attempts based on execution and prediction error feedback.

from arcsolver.solve import ArcSolver

solver = ArcSolver(model, 'bedrock')
solutions = await solver.solve(task, )
