- Genetic algorithm.
- Firefly algorithm.
- Added type erasure for objective functions.
- Added functions in algorithms to change objective functions.
- `linear` module
- Added algebraic multigrid preconditioner used in AMG-CG method.
- `base` module
- Added a macro to check preconditions.
- `util` module
- Added functions to generate gray codes.
- Added a class to check memory allocation in Eigen library.
## Improvements
