QRR

Looped Reasoning Finishes Earlier Than You Think

Sumin Park, T. Konstantin Rusch

The Quotient Recurrent Reasoner adds an exact per-token phase-rotation symmetry so that slow oscillatory motion lives along directions that do not change the reasoning-relevant quotient state, avoiding an oscillation bottleneck in dynamic-depth looped reasoning.

Inside the method

[ Gauge-equivariant recurrent block ] × r → quotient-space readout

Simplified conceptual schematic. Consult the paper for the complete architecture.

Reading note

Reports stable, faster convergence and matches or exceeds recent recurrent reasoning models on Sudoku, Maze and Mini-ARC.
