A P system is a computability model which is biochemically inspired, it is a general distributed model, highly parallel, nondeterministic, based on the notion of a membrane structure. Till this moment, there is no exact idea about the real implementation of P systems. P systems are used in solving NP-complete problems in polynomial time, but with building the whole exponential search space. Cloud computing assume infinite memory and infinite processing power. This paper proposes an algorithm that uses the cloud resources in a fully parallel manner as a step towards P systems implementation, the nondeterminism property of P systems is certainly not maintained. The paper used the SAT problem as the case study.

The automatic diagnosis of breast cancer is an important, real-world medical problem. In this paper we
give an introduction to fuzzy systems, genetic algorithms and artificial immune system, and then we introduce a
hybrid algorithm that gathers the genetic algorithms with the artificial immune system in one algorithm. The genetic
algorithm, the artificial immune system and the hybrid algorithm were implemented and tested on the Wisconsin
breast cancer diagnosis (WBCD) problem in order to generate a fuzzy rule system for breast cancer diagnosis.
The hybrid algorithm generated a fuzzy system which reached the maximum classification ratio earlier than the
two other ones. The motivations of using fuzzy rules incorporate with evolutionary algorithms in the underline
problem are attaining high classification performance with the possibility of attributing a confidence measure
(degree of benignity or malignancy) to the output diagnosis beside the simplicity of the diagnosis system
which means that the system is human interpretable.

E.Nabil, A.Badr, and I.Farag, "A Membrane-Immune Algorithm for Solving the Multiple 0/1 Knapsack Problem", Babes Bolyai, vol. 7, pp. 3-13, 2012. Abstract

In this paper a membrane-immune algorithm is proposed,which is inspired from the structure of living cells and the vertebrate immune system. The algorithm is used to solve one of the most famous combinatorial NP-complete problems, namely the Multiple Zero/One Knapsack Problem. Various heuristics, like genetic algorithms, have been devised to solve this class of combinatorial problems. The proposed algorithm is compared with two genetic based algorithms and overcame both of them. The algorithm is evaluated on nine benchmarks test problems and surpassed both of the genetic based algorithms in six problems, equaled with one of them in two problems and lost in one problem, which indicates that our algorithm surpasses in general genetic algorithms. We claim that the proposed algorithm is very useful in solving similar combinatorial NP-complete problems.

The construction of artificial systems by drawing inspiration from natural systems is not a new idea. The Artificial Neural Network (ANN) and Genetic Algorithms (GAs) are good examples of successful applications of the biological metaphor to the solution of computational problems. The study of artificial immune systems is a relatively new field that tries to exploit the mechanisms of the natural immune system (NIS) in order to develop problem- solving techniques. In this research, we have combined the artificial immune system with the genetic algorithms in one hybrid algorithm. We proposed a modification to the clonal selection algorithm, which is inspired from the clonal selection principle and affinity maturation of the human immune responses, by hybridizing it with the crossover operator, which is imported from GAs to increase the exploration of the search space. We also introduced the adaptability of the mutation rates by applying a degrading function so
that the mutation rates decrease with time where the affinity of the population increases, the hybrid algorithm used for evolving a fuzzy rule system to solve the wellknown Wisconsin Breast Cancer Diagnosis problem (WBCD). Our evolved system exhibits two important characteristics; first, it attains high classification performance, with the possibility of attributing a confidence measure to the output diagnosis; second, the system has a simple fuzzy rule system; therefore, it is human interpretableThe hybrid algorithm overcomes both the GAs and the AIS, so that it reached the classification ratio 97.36, by only one rule, in the earlier generations than the two other algorithms. The learning and memory acquisition of our algorithm was ver-
ified through its application to a binary character recognition problem. The hybrid algorithm overcomes also GAs and AIS and reached the convergence point before them.

E.Nabil, A.Badr, and I.Farag, "A P System Design Using Clonal Selection Algorithm", Universitatis Babe{\c s}-Bolyai Informatica,, vol. LVI, pp. 11-24, 2011. Abstract

Abstract. Membrane Computing is an emergent and promising branch of Natural Computing. Designing P systems is heavy constitutes a difficult
problem. The candidate has often had an idea about the problem soluti onform. On the other hand, finding the exact and precise configurations
and rules is a hard task, especially if there is no tool used to help in the designing process. The clonal selection algorithm, which is inspired from
the vertebrate immune system, is introduced here to help in designing a P system that performs a specific task. This paper illustrates the use of
the clonal selection algorithm with adaptive mutation in P systems design and compares it with genetic algorithms previously used to achieve the
same purpose. Experimental results show that clonal selection algorithm surpasses genetic algorithms with a great difference.
