The numerical solution of differential equations subject to algebraic state constraints and invariants has become increasingly important in several fields of application. Research focused on solving such problems usually centres around the following question: How do you most efficiently utilize the explicit constraint in the discretization scheme of the differential equation? There are two usual lines of attack. The first attempts to build a discretization scheme that embodies the constraint in a direct way. The second augments a generic numerical scheme with additional techniques to enforce the constraints. However, there are significant differences between the corresponding numerical treatments of equalities and inequalities.
In this talk, I will take you from the sometimes tenuous safety of equality constraints to the wild frontiers of inequality constraints by means of several diverse and innovative applications.
