A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. WebThe presented method uses the empirical quadrature procedure (EQP) \cite{yano2024discontinuous} to reduce the cost of the ROM-IFT method for convection-dominated problems containing shocks. ...
