In this paper, a proposed propriety-based path encoding genetic algorithm is applied for the routing problem of CGRA. By mapping Fast Fourier Transform of the butterfly computation to CTaiJi that is a newly developed CGRA, the proposed GA shows good ability to find the good solution. \itemrv{~} \itemcc{} \itemut{coarse-grain reconfigurable architecture; resources-constrained multi-pair shortest path problem in directed graphs; Genetic algorithm; Multi-pair path encoding} \itemli{doi:10.1007/978-3-642-04843-2\_2} \end
