Time-Space Trade-Offs for Computing Euclidean Minimum Spanning Trees

, 2017
In the limited-workspace model, we assume that the input of size $n$ lies in a random access read-only memory. The output has to be reported sequentially, and it cannot be accessed or modified. In addition, there is a read-write workspace of $O(s)$ words,
