  • Although it is possible to use different orderings for preconditioning and matrix-vector multiplication, doing so requires permuting a vector twice in every iteration.

Examples

  • Applying preconditioning to the algorithm improved its overall efficiency in solving complex equations.

  • Instead of doing that, what you'll do is use CG or PCG precondition CG to approximately solve the Newton system.

  • It is a fast algorithm and has benefits in preconditioning as well, as explained in Section 6.

    Academic text (1997)
  • The researcher applied a preconditioning technique to the mathematical model to enhance its convergence speed during simulations.

  • By utilizing preconditioning, the team was able to stabilize the iterative computations and reduce error rates significantly.

Morphology

preconditioning = precondition (semi-transparent) = pre + condition + ing

The immediate base 'precondition' is transparently built from 'pre-' + 'condition', but the specific computational meaning is specialized and may not be fully inferable by average learners.

Etymology

Preconditioning comes from the small part pre- ('before') and the verb condition ('prepare' or 'make ready'). So in computing it means you change a problem beforehand to make the solver work faster and more reliably.
