Testing Algorithm for Global Minima of Test Functions

Click For Summary
SUMMARY

The discussion focuses on testing an algorithm designed to find the global minima of optimization functions, specifically in 2 or 3 dimensions. Participants recommend using the Rastrigin function as a prime example due to its multiple local minima, which presents a challenge for optimization algorithms. The conversation emphasizes the importance of selecting appropriate test functions to evaluate the algorithm's effectiveness in navigating complex landscapes.

PREREQUISITES
  • Understanding of optimization algorithms
  • Familiarity with the Rastrigin function

I'm testing an algorithm to find the global mimina of a function. Can someone give me a few examples of optimization test functions in 2 or 3 dimensions, like the Rastrigin function.

I'm hoping to find functions with several local minima.
