Hi!

Simulating halt deciders (SHDs) simply do not work.

Why? A turing machine should be able to implement ANY algorithm and as
such it is an idealisation, an INFINITE STATE MACHINE (ISM) if you will.

A simulating halt decider (SHD) can only over be implemented as a FINITE
STATE MACHINE (FSM) so is not suitable for a) solving the halting
problem or b) refuting the halting problem proofs.

Olcott has wasted the last 18 years of his life with what he thinks he
invented (SHDs).  Alas the deluded dear hasn't even invented a halt
decider, all he has invented is a particularly useless form of
simulation detector.

Nope. I am including the tape as part of the machine's state just as we
include machine memory as being part of an SHD's state.
