Initial value:

= {
      "Skip resets of the built matrix. This only has an effect in cases "
      "where the operator changes, e.g. between nonlinear-solver iterations. "
      "Skipping resets avoids expensive re-building of the matrix, but comes "
      "at the cost of less accurate preconditioning and thus potentially more "
      "preconditioned iterations. Whether or not this helps convergence "
      "overall is highly problem-dependent."}
