Query: Geometric Algorithms with Limited Workspace: A Survey   In the limited workspace model, we consider algorithms whose input resides in
read-only memory and that use only a constant or sublinear amount of writable
memory to accomplish their task. We survey recent results in computational
geometry that fall into this model and that strive to achieve the lowest
possible running time. In addition to discussing the state of the art, we give
some illustrative examples and mention open problems for further research.
