Directly enforce algebraic condition correctness in ImplicitEuler #2153

Closed ChrisRackauckas closed 4 months ago

ChrisRackauckas commented 4 months ago

Its extrapolation-based error estimator is 0 on algebraic variables, just like Rosenbrock23, so we add the algebraic condition evaluations to the equations just like Rosenbrock23

No, this is on ImplicitEuler
