Abstract: Highlights•A formulation for differential–algebraic equation optimization is proposed.•The formulation uses an implicit function for the algebraic equations and variables.•Convergence reliability is an issue for some dynamic optimization problems.•The implicit function formulation improves convergence reliability.
