This paper introduces subchromosome representations to the linkage learning genetic algorithm (LLGA). The subchromosome representation is utilized for effectively lowering the number of building blocks in order to escape from the performance limit implied by the convergence time model for the linkage learning genetic algorithm. A preliminary implementation to realize subchromosome representations is developed and tested. The experimental results indicate that the proposed representation can improve the performance of the linkage learning genetic algorithm on uniformly scaled problems, and the initial implementation provides a potential way for the linkage learning genetic algorithm to incorporate prior linkage information when such knowledge exists.
