Rule representations significantly impact the search capabilities and decision boundaries in Learning Classifier Systems (LCSs).
Adaptive mechanism introduced to select appropriate rule representation for each rule in LCSs based on different subspaces within the input space.
Flexible rule representation using a four-parameter beta distribution integrated into a fuzzy-style LCS to automatically choose suitable representations for varying subspaces.
Experimental results on real-world tasks show that the LCS with the new rule representation achieves higher test accuracy and generates more concise rule sets.
