Accelerated rule 2 with metering function A, yielding the new rule 6. Accelerated rule 3 with metering function A, yielding the new rule 7. Nested simple loops 2 (outer loop) and 5 (inner loop) with metering function -1+A, resulting in the new rules: 8, 9. Nested simple loops 3 (outer loop) and 5 (inner loop) with metering function -1+A, resulting in the new rules: 10, 11. Removing the simple loops: 1 2 3. popout
