Algorithms in Java

Search algorithms that are appropriate for accessing items from huge files are of immense practical importance. Searching is the fundamental operation on huge data sets,...

As we did in we make the basic assumption that sequential access to data is far less expensive than nonsequential access. Our model will...

A straightforward approach to building an index is to keep an array with keys and item references, in order of the keys, then to use...

To build search structures that can be effective in a dynamic situation, we build multiway trees, but we relax the restriction that every node must...

An alternative to B trees that extends digital searching algorithms to apply to external searching was developed in by Fagin, Nievergelt, Pippenger, and Strong. Their...

The most important application of the methods discussed in this chapter is to construct indexes for huge databases that are maintained on external memory—for example,...
