Use fixed-point iteration to solve a system of nonlinear equations. This is an alternative to the extended Newton's method we have used previously in this section.
Code to find Max/Min of f(x)=2*Sin(x)-x^2/10 using Newton's method
and Secant method alternative.
OPTIMIZE LENGTH OF BEAM TO MINIMIZE A FORCE
Code to solve minimize x^2 + y^2 subject to x+y=2 and 1<=y<=2 using Lagrange Multiplier method.
Note: Application3.f90 code replaced on 1/9/2023 due to bug fix found when converting to Python version.
Program to minimize cost of building a box of fixed volume given the cost of materials using Lagrange multiplier approach.
Golden Search Optimization Method (using only 1 functional evaluation per iteration) for Box Problem in Application 4 using a reduced number of unknowns (by building constraints into cost equation).
This course provides a basic introduction to optimization methods for science and engineering students which is often taught as part of an undergraduate-level numerical methods class. The material covered here is at that level, and includes:
· Newton and Secant methods for one dimensional unconstrained problems.
· Golden search bracketed method for one-dimensional unconstrained problems.
· Univariate search for multi-dimensional unconstrained problems.
· Steepest Ascent Method for multi-dimensional unconstrained problems.
· Newton’s Method for a multi-dimensional unconstrained problem.
· Lagrange multiplier method for multi-dimensional equality constraint problems.
· Lagrange multiplier method for multi-dimensional inequality constraint problems.
· Example problems using the above methods.
Course notes are available for download. Computer codes used to solve these problems, written in both Fortran95 and Python, are also available for download and may be easily modified for your own use.
The material presented is suitable for students in a sophomore or junior level science, technology, engineering and/or mathematics numerical methods class. A background in calculus is necessary, as is the ability to program in a computer language such as Fortran90, C, C++, Python, MatLab, etc.
