“…Related approaches to MP theory and first investigations on MP regression (see later on) were investigated in [8][9][10][11][12][13][14][15][16][17][18]. Applications of MP systems in modeling biological systems, theoretical foundations, and efficient MP regression algorithms were investigated in [19][20][21][22][23][24][25][26][27][28][29][30].…”

The paper reviews some aspects of MP grammars, a particular type of P systems (M stands for Metabolic) consisting of multiset rewriting rules, which were introduced in the context of Membrane Computing, for modeling biological dynamics. The main features of MP theory are recalled, such as the control mechanisms based on regulation functions, MP graphs, representation of oscillatory dynamics, regression algorithms, and MP modeling. Finally, the computational universality of MP grammars is proved by means of Minsky's register machines.

“…Metabolic P systems (MP systems), based on Pȃun's P systems [24], [25], were introduced in [12], [9] for modeling metabolic systems by means of suitable multiset rewriting grammars. An MP system is essentially given by: (i) an MP grammar, which provides the set of variables and rules specifying the system evolution; (ii) the temporal interval τ of the dynamics discretization; (iii) the conventional mole size ν of variable quantities [11].…”

This paper shows the possibility of using Metabolic P systems (MP systems) for chaotic system identificationreconstruction and it compares presented results with previous ones obtained by evolutionary algorithms. An important potentiality of MP theory is given by its powerful computational chaos generation that can be also used as an internal module of evolutionary algorithms by increasing their ability in specific cases of their application. Reported numerical experiments are discussed at the end.

Metabolic P (MP) systems are a class of P systems and are based on metabolic process which is used by living organisms. We review for the purpose of experimental research the MP system development, implementation and modeling. To implement MP systems in dedicated hardware, some specifications need to be determined. We look into the possibility of modeling MP systems in fixed point arithmetic capable hardware and determine the minimal needed bit count for selected MP system model. A way to improve the accuracy of fixed point calculations is proposed, which includes the modification of MP grammar. This modification is done using a simple rule to multiply and divide constants in MP grammar equations. The resulting calculations have more than 250 times smaller error when compared to original calculations. When investigating the performance of MP calculations, it is determined that the time needed for all calculations to finish depends linearly on the number of modeled systems. Metabolinė P sistema yra P sistemos klasė, pagrįsta metabolinio proceso, būdingo gyviesiems organizmams, taikymu. Siekiant pasirengti įgyvendinti MP sistemas aparatine įranga, pateikiama MP sistemų kūrimo, įgyvendinimo ir modeliavimo literatūros analitinė apžvalga. Įvertinama galimybė modeliuoti MP sistemas taikant fiksuotojo kablelio aritmetiką. Imitaciniais eksperimentais nustatytas minimalus pasirinktam MP sistemos modeliui taikyti reikiamas žodžių ilgis. Pasiūlytas būdas fiksuotosios aritmetikos skaičiavimo tikslumui padidinti. Šio būdo esmė yra MP gramatikos modifikavimas pagal konstantų daugybos ir dalybos taisyklę. Skaičiavimus atliekant modifikuota sistema, paklaida esti daugiau nei 250 kartų mažesnė. Tiriant MP sistemų našumą nustatyta, kad skaičiavimo trukmė tiesiškai priklauso nuo modeliuojamų sistemų skaičiaus.
