Industrial Mathematics Final Year Topic: Role of a Line Search in Newton-Type Minimisation on Selected Nonlinear Objectives

This Industrial Mathematics final year project compares a raw Newton step with a stated safeguarded update on bounded test problems.

Generate the Complete Project Read project brief

Why choose this project topic?

A focused study of newton globalisation gives you a specific question in numerical optimisation. It compares a raw Newton step with a stated safeguarded update on bounded test problems. The bounded comparison creates room to explain how your evidence supports an interpretation and where the method has limits.

How does a documented line-search rule change convergence from selected starting points in a nonlinear minimisation problem?

Agree the apparatus or dataset, comparison range and feasible measurement schedule for newton globalisation with your supervisor.

Proposed project objectives

  1. 01Define the materials, variables and comparison conditions for newton globalisation.
  2. 02Choose smooth objectives with known reference minima and record Hessian properties.
  3. 03Evaluate the measurements or model outputs in relation to this question: How does a documented line-search rule change convergence from selected starting points in a nonlinear minimisation problem?

A suggested research approach

Choose smooth objectives with known reference minima and record Hessian properties. Implement the stated step and acceptance rules, compare objective histories and distinguish failed descent directions from failed line-search conditions. Agree the available resources and record uncertainty, deviations from the protocol and any observations that challenge the initial interpretation.

What you will need

  • A documented nonlinear test-function set
  • A consistent Newton and line-search formulation
  • Derivative, descent and termination checks

Keep your project scope clear

Success on test problems does not prove global convergence without the hypotheses of a relevant theorem.
