Cell-like Spiking Neural P systems generating odd numbers - Third example

A third example was proposed in [1], replacing the rules in the previous example, producing 4 spikes and consuming 2 at each step, by the use of the target indication \(in_{all}\), as indicated in the figure:

Model in P-Lingua

The corresponding P-Lingua file is the following:

@model<cell_like_snp>

def main()
{
        @mu = [a*2 []'2 []'3 ]'1;

        [a*2]'1  --> (a*2;inall) "(a{2})+";
        [a]'1  --> (a;out) "(a{2})+";

        [a*2]'2  --> (a*2;out);
        [a*2]'3  --> (a*2;out);

        @mout = 1;
}
