The author discusses an adaptive technique for constructing preconditioners for the conjugate gradient algorithm which is based on the conjugate gradient residual polynomial. She presents an algorithm and results of numerical experiments showing that there are problems for which the method presented can compete with Chebyshev or least square polynomial preconditioners.
