 Model checking algorithms
 =========================
+.. seealso:: `02-analysis.py <https://github.com/moves-rwth/stormpy/blob/master/examples/analysis/02-analysis.py>`_
 
-We can also vary the model checking algorithm.
+Reconsider the model checking example from the getting started guide::
+
+	>>> path = stormpy.examples.files.prism_dtmc_die
+	>>> prism_program = stormpy.parse_prism_program(path)
+    >>> properties = stormpy.parse_properties(formula_str, prism_program)
+    >>> model = stormpy.build_model(prism_program, properties)
+    >>> result = stormpy.model_checking(model, properties[0])
+
+We can also vary the model checking algorithm::
+
+    >>> env = stormpy.Environment()
+    >>> env.solver_environment.set_linear_equation_solver_type(stormpy.EquationSolverType.native)
+    >>> env.solver_environment.native_solver_environment.method = stormpy.NativeLinearEquationSolverMethod.power_iteration
+    >>> result = stormpy.model_checking(model, properties[0], environment=env)
+
+Finally, we allow to change some parameters of the algorithms. E.g., in iterative approaches,
+we allow to change the number of iterations::
+
+    >>> env.solver_environment.maximum_iterations = 3
+    >>> result = stormpy.model_checking(model, properties[0])
+
+Notice that by setting such parameters, the result may be off from the actual model checking algorithm.
