摘要：

A dimensionless discretization parameter LAMBDA controls the accuracy and the computational cost of numerical renormalization-group calculations. For reliable computations of thermodynamical properties of impurities in metals, the upper bound LAMBDA less-than-or-equal-to 3 has long been established. This report discusses a generalization that raises the limit to LAMBDA = 10, yielding the same accuracy with significantly smaller computational cost.
