On evolution of relatively large combinational logic circuits

Evolvable hardware (EHW) (Yao and Higuchi, 1999) is a technique introduced to automatically design circuits where the circuit configuration is carried out by evolutionary algorithms. One of the main difficulties in using EHW to solve real-world problems is the scalability. Until now, several strategies have been proposed to avoid this problem, but none of them completely tackle the issue. In this paper three different methods for evolving the most complex circuits have been tested for their scalability. These methods are bi-directional incremental evolution (SO-BIE); generalised disjunction decomposition (GD-BIE) and evolutionary strategies (ES) with dynamic mutation rate. In order to achieve the generalised conclusions the chosen approaches were tested using multipliers, traditionally used in EHW, but also logic circuits taken from MCNC (Yang, 1991) benchmark library and randomly generated circuits. The analysis of the approaches demonstrated that PLA-based ES is capable of evolving logic circuits of up to 12 inputs. The use of SO-BIE allows the generation of fully functional circuits of 14 inputs and GD-BIE is estimated to be able to evolve circuits of 21 inputs

Evolving PLA structures using evolutionary strategy with dynamic mutation rate

This paper proposes a new evolvable hardware (EHW) technique that allows one to design and optimise relatively complex PLA structures using direct evolutionary process. In order to improve the performance of the evolutionary strategy the authors proposed to introduce the dynamic mutation rate that will be variable to each gene in the chromosome. The experimental results carried out on MCNC benchmarks show that the developed technique significantly outperforms any standard evolvable hardware technique introduced earlier by a number of criteria: time required to evolve logic circuit; evolution of complex circuit using only one direct evolutionary process; guarantee of evolution of fully functional solution

Benchmarking Matching Applications on the Semantic Web

The evaluation of matching applications is becoming a major issue in the semantic web and it requires a suitable methodological approach as well as appropriate benchmarks. In particular, in order to evaluate a matching application under different experimental conditions, it is crucial to provide a test dataset characterized by a controlled variety of different heterogeneities among data that rarely occurs in real data repositories. In this paper, we propose SWING (Semantic Web Instance Generation), a disciplined approach to the semi-automatic generation of benchmarks to be used for the evaluation of matching applications
