The DIRAC code for relativistic molecular calculations

TL;DR: DIRAC as discussed by the authors is a freely distributed general-purpose program system for one-, two-, and four-component relativistic molecular calculations at the level of Hartree-Fock, Kohn-Sham (including range-separated theory), multiconfigurational self-consistent field, multireference configuration interaction, electron propagator, and various flavors of coupled cluster theory.
Journal ArticleDOI

An improved chain of spheres for exchange algorithm.

TL;DR: In this article, the authors describe a more accurate and efficient variant of the chain-of-spheres algorithm (COSX) for exchange matrix computations, which is obtained with new grids that were developed using global optimization techniques.
Journal ArticleDOI

Improvements on the minimax algorithm for the Laplace transformation of orbital energy denominators

TL;DR: A robust and non-heuristic algorithm that finds all extremum points of the error distribution function of numerically Laplace-transformed orbital energy denominators and demonstrates that 3 times less function evaluations are required altogether when applying it to typical non-relativistic and relativistic quantum chemical systems.
