explicit method
In numerical analysis, a method where the state at a later time is computed directly from the current state, without solving an equation. Contrasts with 陰解法 (implicit method).
The explicit method is simple to compute, but it can become unstable if the time step is too large.
From 陽 (explicit, positive) + 解法 (solution method). The term is a direct translation of the English 'explicit method' in numerical analysis.
