| Abstract: | An error analysis is provided for discrete Lagrangian cell problems where the exact objective function for each cell is approximated by a simpler expression. Easily-calculated rigorous and heuristic bounds are given for the error in the value of the objective function. The solution itself, however, can be significantly distorted. |
