TLDR
A small gate array is evolved extrinsically to carry out a low pass filtering task defined over fifteen different frequencies, which includes signals with noise added and with frequencies which are not in the training set.Abstract:
A small gate array is evolved extrinsically to carry out a low pass filtering task defined over fifteen different frequencies The circuit is evolved by assessing its response to digitised sine waves Two different fitness functions are contrasted One is based on computing the sum of the absolute differences between the actual response and that desired, the other is defined by examining characteristics of the discrete Fourier transform of the output The gate arrays possess some linear properties, which means that they are capable of filtering composite signals which have not been encountered in training This includes signals with noise added and with frequencies which are not in the training setread more

TL;DR: A neutral search strategy that allows the fittest genotype to be replaced by another equally fit genotype (a neutral genotype) is examined and compared with non-neutral search for the Santa Fe ant problem and the neutral search proves to be much more effective.
Cartesian Genetic Programming.
TL;DR: The genotype–phenotype mapping used in CGP is one of its defining characteristics and its types are decided by the user and are listed in a function look-up table.

Digital Signal Processing: A Practical Approach
TL;DR: This book covers a number of DSP techniques that are of particular relevance to industry such as adaptive filtering and multirate processing, and offers modern coverage of the fundamentals, implementation and applications of digital signal processing techniques from a practical point of view.
A Survey of Evolution Strategies.
TL;DR: Evolution Strategies are algorithms which imitate the principles of natural evolution as a method to solve parameter optimization problems and adaptation of the strategy parameters for the mutation variances as well as their covariances are described.

Use of minimum-adder multiplier blocks in FIR digital filters
TL;DR: Three new algorithms for the design of multiplier blocks are described: an efficient modification to an existing algorithm, a new algorithm giving better results, and a hybrid of these two which trades off performance against computation time.

On the Automatic Design of Robust Electronics Through Artificial Evolution
TL;DR: After defining an ‘operational envelope’ of robustness, the feasibility of performing fitness evaluations in widely varying physical conditions in order to provide a selection-pressure for robustness is demonstrated and preliminary experimental results are encouraging.
