In this paper, we study the restarted Krylov subspace method, which istypically represented by the GMRES(m) method. Our work mainly focused on theamount of change in the iterative solution of GMRES(m) at each restart. Wepropose an extension of the GMRES(m) method based on the idea of projection.The algorithm is named as LGMRES. In addition, LLBGMRE method is also obtainedby adding backtracking restart technology to LGMRES. Theoretical analysis andnumerical experiments show that LGMRES and LLBGMRES have better convergencethan traditional restart GMRES(m) method.
