We prove the existence of solutions to our equation. Also, we consider an optimal control problem without uniqueness of solutions to the state system. Then, we prove the existence of an optimal control which minimizes the nonlinear cost functional. Moreover, we apply our general result to some model problem.application/pdfeng510Optimal controldoubly nonlinear evolution equationssubdifferentialswithout uniquenessReport
