- All Implemented Interfaces:
AutoCloseable
,Problem
The Rastrigin function. For a problem with D variables, this highly multimodal function has approximately 10^D
local optima. It is not intended for this function to be used directly since the BBOB test suite applies
additional transformations to the test functions.
Properties:
- Separable
- Multimodal

evaluate
Description copied from interface:Problem
Evaluates the solution, updating the solution's objectives in place. Algorithms must explicitly call this method when appropriate to evaluate new solutions or reevaluate modified solutions.- Parameters:
solution
- the solution to be evaluated
