These methods were developed around 1900 by the German mathematicians Carl … See more The most widely known member of the Runge–Kutta family is generally referred to as "RK4", the "classic Runge–Kutta method" or simply as "the Runge–Kutta method". Let an See more The family of explicit Runge–Kutta methods is a generalization of the RK4 method mentioned above. It is given by $${\displaystyle y_{n+1}=y_{n}+h\sum _{i=1}^{s}b_{i}k_{i},}$$ See more A Runge–Kutta method is said to be nonconfluent if all the $${\displaystyle c_{i},\,i=1,2,\ldots ,s}$$ are distinct. See more All Runge–Kutta methods mentioned up to now are explicit methods. Explicit Runge–Kutta methods are generally unsuitable for the solution of stiff equations because … See more Adaptive methods are designed to produce an estimate of the local truncation error of a single Runge–Kutta step. This is done by … See more Runge–Kutta–Nyström methods are specialized Runge-Kutta methods that are optimized for second-order differential equations of the following form: See more In general a Runge–Kutta method of order $${\displaystyle s}$$ can be written as: $${\displaystyle y_{t+h}=y_{t}+h\cdot \sum _{i=1}^{s}a_{i}k_{i}+{\mathcal {O}}(h^{s+1}),}$$ See more
