## Reducing the Cost of Total Derivative Solves Using Advanced Features¶

There are a number of special cases where a model has a particular structure that can be exploited to
reduce the cost of linear solves used to compute total derivatives. You can learn details of how to determine if
your problem has the necessary structure to use one of these features, or how to restructure your problem to
make use of them in the :ref:`Theory Manual entry on how OpenMDAO computes total derivatives<total_derivs_theory>`
