An additional unitary transformation can be applied on the system to accelerate the convergence in some computational schemes.

The computational scheme is like climbing a bamboo tree, going up and up step by step at measured equal heights.

Madhava prescribes this numerically efficient computational scheme in the following words ( translation of verse 2.437 in " Yukti-dipika " ):

The combination of the DMFT with material-specific approaches, such as the " Local Density Approximation " ( LDA ) to the density functional theory, led to a new computational scheme, often referred to as LDA + DMFT, for the investigation of strongly correlated materials.
