computational problem are so large, that there is not time to read them in their entirety. However, if one is only interested in small
parts of the output at any given time, is it really necessary to solve the
entire computational problem? Is it even necessary to view the whole input? We
survey recent work in the model of
"local computation algorithms" which for a given input,
supports queries by a user to values of specified
bits of a legal output. The goal is to
design local computation algorithms in such a way that very little of the input
needs to be seen in order to determine the value of any single bit of the
output. In this talk, we survey a series of results on local computation
algorithms for finding sparse connected subgraphs and sparse spanners.</font></div><p
