... Hinton and Nowlan's results demonstrate it, (c) how Ackley and Littman's results demonstrate it, and (d) how Ackley and Littman's approach compares with that of Hinton and Nowlan. 3. ... important to define them in a more rigorous and quantitative way, and to develop methods to detect and measure them. In other words: How can we decide if an observed system is evolving?...

... even in Hinton and Nowlan's simple model. Computer simulations such as theirs can help us to understand and to measure such tradeoffs. More detailed analyses of Hinton and Nowlan's model ... or Otto 1991), but Collins and Jefferson's is one of the few to use a microanalytic method based on a genetic algorithm. (For other GA−based models, see Miller and Todd 1993, Todd a...

How can we ... parallelism than the latter, since an instance of the former contains more schemas than an instance of the latter (2 100 versus 2 30 ).
