5 Conclusions Learning Classifier Systems use GAs to discover appropriate rules. This paper has presented a simple Markov model of the GA in LCSs, with the aim of examining the Simple Markov Models of the Genetic Algorithm in Classifier Systems (a) (b) Fig. 2. Probabilities for the two multi-step tasks in Fig. 1 under a niche scheme. For clarity, the absorbing states are not shown here. 33 34 L. Bull effects of different types of interdependence between niches in multi-step tasks. It has been shown that the existence of partner rule variance, whereby optimal behaviour in one niche changes with a change in behaviour in another niche of the task, can have significant and detrimental effects on expected behaviour.

That is, a direct correlation is seen between the increase in probability of increasing the number of overgeneralists and the magnitude of increase in pm. This result therefore appears to support the findings of Bull et al. [2000] in that the change in behaviour under a raised mutation rate seems more marked under accuracy-based fitness than prediction. Of course, fitness inheritance and rule reinforcement are also very different in XCS than a standard LCS and these aspects may also be contributing to the change in behaviour - this is currently under investigation.
