On the boundaries of solvability and unsolvability in tag systems. Theoretical and Experimental Results.

Liesbeth De Mol

Several older and more recent results on the boundaries of solvability and unsolvability in tag systems are surveyed. Emphasis will be put on the significance of computer experiments in research on very small tag systems.
