Dictionary Indexes,l down to some basic algorithmic primitives which involve a large dictionary of strings having variable length. Typical examples include: pattern matching (exact, approximate, with wild-cards, .), the ranking of a string in a sorted dictionary, or the selection of the .-th string from it. While it i

However they are quite often used (probably, unconsciously!) by programmers to replace long strings with unique . which are easier and faster to be processed and compressed. In this context ranking a string means mapping it to its unique ., whereas selecting the .-th string means retrieving it from its . (i.e. its ranked position .

In this monograph we introduce solutions that overcome this dichotomy. We start by presenting the use of optimization techniques to improve the compression of
