Table 3 Updates of the open stack and close table during heuristic searches of the two-phase ML decoder
From: A low-complexity maximum likelihood decoder for tail-biting trellis
Step | Open stack | Close table | Complexity |

3 | {(1, 3, 2, 0.986), (1, 1, 2, 1.234)} | {(1, 1, 0), (1, 2, 1)} | {(6, 10)} |
4 | {(1, 1, 2, 1.234), (1, 3, 3, 1.277)} | {(1, 1, 0), (1, 2, 1), (1, 3, 2)} | {(6, 13)} |
5 | {(1, 2, 3, 1.234), (1, 3, 3, 1.277)} | {(1, 1, 0), (1, 2, 1), (1, 3, 2), (1, 1, 2)} | {(6, 16)} |
