Similar to the TI-ADGA, we define a set of convergence thresholds for determining when the TD-ADGA grid is converged. When the convergence is checked in TD-ADGA we compare the TD-ADGA integral at the current time T mn I mn ℓ mn (t curr ), with the TD-ADGA integrals obtained at a previous time T mn I mn ℓ mn (t prev ). Thus, an integration box in the TD-ADGA grid is considered converged and should not be sub-divided if
