From: r.e.s. on 19 Nov 2007 17:45 I've posted an article at http://geocities.com/r_e_s_01/cmm/ showing how the Cocke-Minsky scheme for simulating 2-symbol TMs by 2-tag systems can be extended to simulate k-symbol TMs by k-tag systems. Included are a few applications to some small UTMs, with the curiosity of deriving rather obese, yet "smallest"-known (!), universal tag systems. Comments are welcome. --r.e.s. |
