Term: Multistep Methods
Definition: Techniques that utilize multiple previous points to compute the next value of a solution for algorithms dealing with ODEs.
Term: AdamsBashforth Method
Definition: An explicit predictor-based multistep method that estimates future values of a function using its previous derivative values.
Term: Local Truncation Error (LTE)
Definition: The error made in one step of a numerical method, indicating how the numerical solution compares to the exact solution at that step.
Term: Global Error
Definition: The total error of a numerical solution over all steps, summing up the local errors.
Term: Explicit Methods
Definition: Numerical methods where the next value is calculated directly from known previous values.
Term: Implicit Methods
Definition: Numerical methods where the next value depends on itself, leading to potential complexities in solving.
