This edition of TMBR is in progress and has not yet been released. Please add any notes you think may be relevant (including in the form a of a TODO with a link to any relevant Discord discussion).
This is the first edition of TMBR in 2026.
Champions
- Azerty discovered a new BLB(3,3) champion (
1RB2RB1LA_2LC0LB2LB_2RC2RA0LC(bbch)) which blanks the tape after running for more than 1042,745 steps.
BB Adjacent
- Uniform-Action Busy Beavers were introduced, and lower bounds have been given up to BBu(6) (with BBu(3)=17)
Holdouts
- BB(6): 2 solved machines.
- Progress has been made in reducing the list of machines not simulated up to 1e13, by Alistaire: see spreadsheet. Current count: 210. (Total reduction: 68. 38 machines[1][2][3][4][5][6][7][8][9][10][11][12][13][11 more][4 more][10 more][11 more][17 more] simulated out, plus 2 solved machines).
- Alistaire found a halting machine in the list mentioned above, see Discord. Approximate score: 4e12. Later, he found another halting machine in the same list, see Discord - approximate score: 1.5e18.
