Nondeterministic Bottom-up Pyramid Acceptors.
Akira Nakamura, Charles R. Dyer · 1977
Several properties and capabilities of nondeterministic bottom-up pyramid cellular acceptors (NBPA's) are presented. NBPA's are a special case of the pyramid cellular acceptors. The main result is that the class of languages accepted by nondeterministic bounded cellular array acceptors is the same as that accepted by NBPA's.
