How do truncation errors, rounding errors, and conditioning collectively influence the stability of numerical algorithms, and under what theoretical conditions can an unstable algorithm still produce acceptable results?
Students should:
a) Define truncation error formally.
b) Derive truncation error for at least one example:
c) Show how truncation error depends on step size h.
d) Prove the order of accuracy for the chosen method.
Expected demonstration:
Mathematical derivation using Taylor expansion and Big-O notation.
Students should:
a) Define floating-point representation and machine epsilon.
b) Explain how rounding errors accumulate in iterative algorithms.
c) Derive error bounds caused by floating-point arithmetic.
d) Provide an example (e.g., subtraction of nearly equal numbers).
Expected demonstration:
Model floating-point arithmetic as:
fl(x)=x(1+),??machine
and propagate this through an algorithm.
Students should:
a) Define well-conditioned vs ill-conditioned problems.
b) Define the condition number of a function and of a matrix.
c) Derive the condition number for:
d) Interpret geometrically what a large condition number implies.
Expected demonstration:
(A)=AA1
Show sensitivity of solution to perturbations.
Students must:
a) Explain why conditioning is a property of the problem.
b) Explain why stability is a property of the algorithm.
c) Provide examples where:
Expected demonstration:
Formal reasoning, possibly using linear systems.
Students should:

b) Define backward error.
c) Show how backward stability is used to assess algorithms.
d) Demonstrate backward error analysis for:
Expected demonstration:
Prove that computed solution solves a slightly perturbed problem.
Students must:
a) Construct a total error model:
Total Error=Truncation Error+Rounding Error
b) Show how decreasing step size reduces truncation error but increases rounding error.
c) Derive an expression for optimal step size balancing both errors.
Expected demonstration:
Minimize error expression using calculus.
Students should analyze one algorithm (choose one):
They must:
a) Identify all three error sources.
b) Analyze how they interact.
c) Discuss stability implications.
This is the deeper theoretical part.
Students must investigate:
They should analyze and justify:
They must:
a) Provide at least one mathematical example.
b) Use error bounds to justify conclusions.
c) Provide a counterexample where instability destroys accuracy.
Students should conclude by addressing:
