ButcherSimplify


is an option to RungeKuttaOrderConditions that specifies whether to apply Butcher's row- and column-simplifying conditions.
  • Butcher's row- and column-simplifying assumptions reduce the set of necessary and sufficient trees for an order p method with s stages.
  • For implicit methods, all trees are reduced to quadrature type together with subsidiary row- and column-simplifying conditions.
  • For explicit methods, the restriction for implies positivity of the weights .
