Webb8 nov. 2024 · Specifically, implicit or explicit methods are defined by the contexts in which they are meant to be used. Implicit code can be a very nice experience if things are well named as it keeps things simple. However, implicit code, code doing things behind the scenes for you, can also be a difficult issue to solve when done wrong. WebbIn our previous study, the Decoupled Implicit Method for Efficient Network Simulation (DIMENS) method was proposed based on the ‘Divide-and-Conquer Approach’ ideal, and its computational speed was obviously high.
