Thresholding 2D Images with Cell-like P Systems
(Romanian Academy, 2010)
Thresholding is the process of splitting a digital image into sets of pixels in order to make it easier to analyze. Pixels are ordered according to a scale of one of their features as brightness or color and the ¯nal ...

A parallel algorithm for skeletonizing images by using spiking neural P systems
(Elsevier, 2013-09)
Skeletonization is a common type of transformation within image analysis. In general, the image B is a skeleton of the black and white image A, if the image B is made of fewer black pixels than the image A, it does preserve ...

Two-hidden-layer Feedforward Neural Networks are Universal Approximators: A Constructive Approach
(Cornell University, 2019)
It is well known that Artificial Neural Networks are universal approximators. The classical result proves that, given a continuous function on a compact set on an n-dimensional space, then there exists a one-hidden-layer ...

Solving the 3-COL problem by using tissue P systems without environment and proteins on cells
(ELSEVIER SCIENCE INC, 2018)
The 3-COL problem consists on deciding if the regions of a map can be coloured with only three colors bearing in mind that two adjacent regions must be coloured with different colors. It is a NP problem and it has been ...

Local Search with P Systems
(IGI GLOBAL, 2011)
Local search is currently one of the most used methods for finding solutions in real-life problems. It is usually considered when the research is interested in the final solution of the problem instead of the how the ...

A Rete-based algorithm for rule selection in P systems
(Old City Publishing, Inc., 2013)
The Rete algorithm is a well-known pattern matching algorithm conceived to make rule-based production system implementa tions more efficient. It builds a directed acyclic graph, represent ing higher-level rule sets, that ...
