User:RobinCodes/Machines at the Edge

Some machines are right at the edge of computability. This means that they are computationally tractable to simulate, but they are literal energy vampires. There are a few such machines that have been found, but only two have been collected for now.

6x2 Machines

1RB1RE_1LC1LD_---1LA_1LB1LE_0RF0RA_1LD1RF (bbch)

• Would take a few weeks with ~10 TB of memory.
• 50% chance of halting based on H^114e12(10) mod 4.
• Mechanism: approximately B(m) ~ B(H^m(10)).

1RB0LA_0RC0RB_1LD1LA_1LC1RE_1RF0RD_1LC--- (bbch)

• Around a day with somewhere in [100, 1000] GB of memory.
• Expected to halt on the order of one trillion iterations.
• Mechanism: pipe Hydra residues into another very chaotic machine.
