+### Test functions
+
+In the `fireflyalgorithm.problems` module, you can find the implementations of 33 popular optimization test problems.  Additionally, the module provides a utility function, `get_problem`, that allows you to retrieve a specific optimization problem function by providing its name as a string:
+
+```python
+from fireflyalgorithm.problems import get_problem
+
+# same as from fireflyalgorithm.problems import rosenbrock
+rosenbrock = get_problem('rosenbrock')
+```

 ### Command line interface
 
 The package also comes with a simple command line interface which allows you to evaluate the algorithm on several
