Abstract: The problem of finding small universal spiking neural P systems was
recently investigated by Andrei Păun and Gheorghe Păun, for
spiking neural P systems used as devices computing functions and as devices
generating sets of numbers. For the first case, a universal spiking neural P
system was produced by using 84 neurons for standard rules and using 49 neurons
for extended rules. For spiking neural P systems used as generators of sets of
numbers, a universal system with standard rules having 76 neurons, and one with
extended rules having 50 neurons were obtained. In this paper, we continue the
study of small universal spiking neural P systems and we improve in the number
of neurons as follows. The small universal spiking neural P systems use 67
neurons for standard rules and 41 neurons for extended rules in the case of
computing functions, and 63 neurons for standard rules and 41 neurons for
extended rules in the case of generating sets of numbers.
