- Use auto in places where code clarity is improved or identical. - Replace trivial constructors and destructors with default. - Use true random for random generation. - Use std::string_view where it is valid to do so. - Apply const where it is valid to do so. - Use references where it is valid to do so. - Manually optimize memory usage with std::move and std::copy. - Opt for memory efficient containers where the size is known ahead of time.
