Subject: Turing machine demo?
Print | View thread | Show original | Report this message | Find messages by this author
Has anyone out there written a nice demo
of a Turing machine[1] in Forth? It could
probably be easily and elegantly done
with JVN's finite state machine code, but
maybe that's overkill. The demo should
be capable of accepting a series of user
entered program and showing the results
after each cycle. Perhaps it's a standard
exercise in an intro CS course to write
such a virtual machine.

[1] For those like me, who have not much CS
background, a Turing machine is the prototype
computing machine described by Alan Turing
in a 1936 paper. It is a simple state
machine with just a few instructions (less
than 10), but the Church-Turing assertion
states that it can be programmed to carry
out any algorithm, i.e. it's equivalent to
any digital computer that can be conceived.
Hope I got that right :)
