Generally, Adams methods are superior of output at many points is needed.

The Adams methods are useful to reduce the number of function calls, but they usually require more CPU time than the Runge-Kutta methods.

Multistep method does not improves the accuracy of the answer at each step.

Multistep methods attempt to gain efficiency by keeping and using the information from previous steps rather than discarding it. Consequently, multistep methods refer to several previous points and derivative values.

In Runge – Kutta Method, we do not need to calculate higher order derivatives and find greater accuracy.

R.K Methods do not require prior calculation of higher derivatives of y(x) ,as the Taylor method does. Since the differential equations using in applications are often complicated, the calculation of derivatives may be difficult
