Lamarckian Evolution , The Baldwin E ectand Function

We compare two forms of hybrid genetic search. The rst uses Lamarckian evolution, while the second uses a related method where local search is employed to change the tness of strings, but the acquired improvements do not change the genetic encoding of the individual. The latter search method exploits the Baldwin eeect. By modeling a simple genetic algorithm we show that functions exist where si...

The Baldwin E ect on the Evolution of Associative Memory

|We apply genetic algorithms to the Hop eld model of associative memory. Previously, we reported that a genetic algorithm evolves a network with random synaptic weights to store eventually a set of random patterns. In this paper, we present the Baldwin e ect on the evolution enhances the storage capacity.

Telling it like it is

Following a year of public engagement activities associated with the Royal Institution Christmas Lectures, Alison Woollard explains why scientists need to communicate with the public.

Telling it like it is

With the amazing successes that have been reported over the past 10 years, it is easy for researchers in therapeutic ultrasound to be seduced by the appeal of biological and clinical studies but understanding the biology alone is insufficient. All good science requires repeatability, and developing a successful therapy is no different. It is imperative from both a scientific and a commercial pe...
