Evolution—the Extended Synthesis

Extended genomes: symbiosis and evolution

Many aspects of an individual's biology derive from its interaction with symbiotic microbes, which further define many aspects of the ecology and evolution of the host species. The centrality of microbes in the function of individual organisms has given rise to the concept of the holobiont-that an individual's biology is best understood as a composite of the 'host organism' and symbionts within...

Tuning of Extended Kalman Filter using Self-adaptive Differential Evolution Algorithm for Sensorless Permanent Magnet Synchronous Motor Drive

In this paper, a novel method based on a combination of Extended Kalman Filter (EKF) with Self-adaptive Differential Evolution (SaDE) algorithm to estimate rotor position, speed and machine states for a Permanent Magnet Synchronous Motor (PMSM) is proposed. In the proposed method, as a first step SaDE algorithm is used to tune the noise covariance matrices of state noise and measurement noise i...

Design of Neural Networks by the Extended Differential Evolution Algorithm

This paper proposes an improved evolutionary method to optimize the beta function neural network (BBFNN) in order to approach target function from a set of input-output. The procedure allows the application of the Improved Differential Evolution (IDE) as the optimization engine of our algorithm to improve the solution of the problem at hand by including the extended mutation and crossover opera...

Toward Code Evolution By Artificial Economies Extended Abstract

We have begun exploring code evolution by artificial economies. We implemented a reinforcement learning machine called Hayek2 consisting of agents, written in a machine language inspired by Ray’s Tierra, that interact economically. The economic structure of Hayek2 addresses credit assignment at both the agent and meta levels. Hayek2 succeeds in evolving code to solve Blocks World problems, and ...
