Adam’s type block methods for solving neutral delay differential equation with constant and panthograph delay

The numerical solutions for Neutral Delay Differential Equation (NDDE) have been studied in this thesis. Two numerical methods which are known as an explicit multi- step block method and a hybrid multistep block method have been introduced. The multistep block methods will be implemented in s...

Two numerical methods which are known as an explicit multi- step block method and a hybrid multistep block method have been introduced. The multistep block methods will be implemented in solving NDDE with constant and pantograph delay types using constant step size. Both methods have been derived by using Taylor series polynomial where the implementations of the methods are based on predictor-corrector formulas. In this research, the source codes for the numerical solutions were written in C language. In the developed algorithm, the delay terms have been approximated by using divided difference formulas depending on the ap- plicability of both methods in every iteration.
