Explicitly correlated F12 theories have been developed in the past decades to rectify the slow convergence of dynamical electron correlation models with basis size, in which additional two-electron integrals over F12 kernels are required. This article reviews some existing algorithms for these integrals, including the author’s attempt, and leave an open question: what will be the most efficient algorithm (and who wants to implement it into a tightly optimized code)?
