Efficiency of Tissue P Systems with Cell Separation
(Fénix Editora, 2009)
The most investigated variants of P systems in the last years are cell-like models, especially in terms of efficiency. Recently, different new models of tissue-like (symport/antiport) P systems have received important ...

A Tissue P Systems Based Uniform Solution to Tripartite Matching Problem
(IOS Press, 2011)
A tissue P system with cell division is a computing model which has two basic features: intercellular communication and the ability of cell division. The ability of cell division allows us to obtain an exponential amount ...

Membrane Computing Schema: A New Approach to Computation Using String Insertions
(Springer, 2009)
In this paper, we introduce the notion of a membrane computing schema for string objects. We propose a computing schema for a membrane network (i.e., tissue-like membrane system) where each membrane performs unique type ...

Optimizing ligand conformations in flexible protein targets: amulti-objective strategy
(Springer, 2020)
Finding the orientation of a ligand (small molecule) with the lowest binding energy to the macromolecule (receptor) is a complex optimization problem, commonly called ligand–protein docking. This problem has been usually ...

Solving 3-COL with Tissue P Systems
(Fénix Editora, 2006)
In the literature, several examples of the efficiency of cell-like P systems in order to solve NP-complete problems in polynomial time can be found. Recently, various new models of tissue-like P systems have received ...

Efficient simulation of tissue-like P systems by transition cell-like P systems
(Springer, 2009)
In the framework of P systems, it is known that the construction of exponential number of objects in polynomial time is not enough to efficiently solve NP-complete problems. Nonetheless, it could be sufficient to create ...

A P-Lingua Programming Environment for Membrane Computing
(Springer, 2009)
A new programming language for membrane computing, PLingua, is developed in this paper. This language is not designed for a speci c simulator software. On the contrary, its purpose is to o er a general syntactic framework ...

Island Based Distributed Differential Evolution: An Experimental Study on Hybrid Testbeds
(IEEE Computer Society, 2008)
This paper presents a new distributed Differential Evolution (dDE) algorithm and evaluates it according to the standard procedure set in the special session of continuous optimization of CEC’05. We statistically validate ...

Qom—A New Hydrologic Prediction Model Enhanced with Multi-Objective Optimization
(MDPI, 2019)
The efficient calibration of hydrologic models allows experts to evaluate past events in river basins, as well as to describe new scenarios and predict possible future floodings. A difficulty in this context is the need ...
