In this paper, we study the allocation of files in a star network. Unlike previous algorithms which assume that files are independently accessed and independently assigned, the interaction of files during the processing of queries is directly incorporated into our cost model. We present an adaptive algorithm, which is much faster than existing algorithms on file allocation, obtains solutions which are on the average only 0.1 percent away from the optimal solutions, and possesses many desirable properties such as the satisfaction of some necessary and sufficient conditions for file allocation.
