The author analyses the Conjugate Gradient Normal Residual algorithm (CGNR) and proves that it is both residual minimizing and error reducing. Then, by using a polynomial preconditioning he constructs an adaptive version of the CGNR algorithm. Numerical tests and comparisons with GMRES and classical CGNR algorithms are also reported.
