Josh Goings’ first paper since joining the group (and first paper ever!) was just accepted for publication in Advances in Quantum Chemistry. The paper is titled “Accelerating Wavefunction Optimization using Quasi-Newton DIIS” and presents a new method for wavefunction optimization that incorporates the direct inversion in the iterative subspace algorithm.
