A remark on the optimal mesh and the optimal polynomial degree distribution in solving 1D boundary value problem by the hp-FEM
solution.To this end, a constrained optimization method is applied. Since the optimization of the polynomial degree distribution leads to a combinatorial optimization problem, solving the entire optim...

Convergence rates of moment-sum-of-squares hierarchies for optimal control problems
We study the convergence rate of the moment-sum-of-squares hierarchy of semidefinite programs for optimal control problems with polynomial data. It is known that this hierarchy generates polynomial under-approximations to t...
