T. Tokihiro et al., FROM SOLITON-EQUATIONS TO INTEGRABLE CELLULAR-AUTOMATA THROUGH A LIMITING PROCEDURE, Physical review letters, 76(18), 1996, pp. 3247-3250
We show a direct connection between a cellular automaton and integrabl
e nonlinear wave equations. We also present the N-soliton formula for
the cellular automaton. Finally, we propose a general method for const
ructing such integrable cellular automata and their N-soliton solution
