Here we are in the darkest forest.
This forest consists of nothing but different Nyström trees.
Consider the numerical solution of a initial value problem
(IVP) for the system of second-order differential equations:
y'' = f(x,y),
A Nyström tree is an equation of condition for the
explicit Runge-Kutta-Nyström(RKN)-type methods.
The most efficient numerical methods
The scientific community seems to be agreed that
the explicit RKN-types are the most efficient methods
for solving the IVP. On this website I present the best
RKN-type methods I had made in
They are mentioned in ,
but are not yet published.
there is published this forest. In

explains his computer program for generating trees.
