A Modified Third-Order Block Numerical Integration Technique for First Order Stiff and Oscillatory Differential Equations

This paper proposes a modified two-point block backward differentiation formula (MBBDF) for the numerical solution of highly stiff and oscillatory ordinary differential equations. The method achieves third-order accuracy with a reduced error constant and computes two solution values simultaneously at each step. For the...
