# Welcome to the DSI Utilities!
## Introduction
The DSI utilities are a mishmash of classes accumulated during the last
twenty years in projects developed at the DSI (Dipartimento di Scienze
dell'Informazione, e.g., Information Sciences Department), now DI
(Dipartimento di Informatica, i.e., Informatics Department), of the
Università degli Studi di Milano.

Lesser General Public License

## Building
You need [Ant](https://ant.apache.org/) and [Ivy](https://ant.apache.org/ivy/).
Then, run `ant ivy-setupjars jar`.
## Papers
* A [paper](http://vigna.di.unimi.it/papers.php#BoVMSJ) about the
high-performance reimplementation of strings provided by the versatile
class
[`MutableString`](https://github.com/vigna/dsiutils/blob/master/src/it/unimi/dsi/lang/MutableString.java),
and _compact approximators_, the randomized data structure used in
[`TextPattern`](https://github.com/vigna/dsiutils/blob/master/src/it/unimi/dsi/util/TextPattern.java)
to represent bad-character shifts.
* A [paper](http://vigna.di.unimi.it/papers.php#VigBIRSQ) about the
broadword implementation of select queries implemented in
[`Fast.select()`](https://github.com/vigna/dsiutils/blob/master/src/it/unimi/dsi/bits/Fast.java).
* Papers about the [pseudorandom number
generators](http://prng.di.unimi.it/) included can be found
[here](http://vigna.di.unimi.it/papers.php).
