Hello world

Description

This example intends to be a starting point to understand the functioning of P-Lingua and MeCoSim (custom apps, models, scenarios), along with a first approach to the modelling of transition P systems in P-Lingua.

Model in P-Lingua

The corresponding P-Lingua code is the following:

@model<transition>

/* Transition P system model. */

def main()
{
        /* Membrane structure. */
        @mu = []'1;

        /* Initial multiset in membrane labelled by 1. */
        @ms(1) = a*1;

        /* Rules in membrane labelled by 1. */
        [a --> c]'1;
        [a --> b]'1;
}

Files

• The example does not need input data from any user nor speficic interesting outputs, so it can be run from the general app yet available and pre-loaded in MeCoSim.
• Model file, P-Lingua file with the code above.
• As in the case of the app, no scenario file with specific input is needed, so the general dummy scenario file can also be used.
