Class Ret.pfqnSensLinearizer

jline.io.Ret.pfqnSensLinearizer

Enclosing class:

Ret

public static class Ret.pfqnSensLinearizer
extends Object

Result type for the approximate higher moments of the per-station total queue lengths of a closed product-form network, computed by the LINEARIZER-2 / LINEARIZER-3 algorithms of Pfqn_sens_linearizer.

The fields mirror Ret.pfqnSensMom, of which this is the polynomial-time approximate counterpart, with one difference of interpretation: CovAsym is NOT expected to sit at roundoff here, because the Linearizer fixed point does not enforce the symmetry that the product form guarantees. It is a useful measure of the approximation error.
