One of the popular tensor iterative Krylov subspace methods is the CMRH method based on tensor format, called CMRH-BTF method. Due to the reduction of storage and computational costs, the CMRH-BTF method is used with restarting. A drawback of restarting is slowdown of the convergence. In this paper, we present a variant of the restarted CMRH-BTF (CMRH-BTF(m)) method with retaining some Krylov subspace information of the previous cycles. A numerical experiment demonstrates the effectiveness of this method.
