The Pseudopotential Algorithm for Real‐Space Electronic Calculations (PARSEC) is a software package written by a team consisting of materials physicists and computer scientists over approximately one decade. During this period, the algorithms used in PARSEC have undergone a series of improvements. This paper reviews the nature of the eigenvalue problems encountered in solving the Kohn–Sham equations and discusses the evolution of the diagonalization methods used in PARSEC.
