Synopsis: Pure priority search queues
|
||||
Category: Data Structures
|
||||
Build-type: Simple
|
||||
Cabal-version: >=1.8
|
||||
|
||||
Description:
|
||||
The psqueues package provides
|
||||
<http://en.wikipedia.org/wiki/Priority_queue Priority Search Queues> in
|
||||
three different flavors.
|
||||
.
|
||||
* @OrdPSQ k p v@, which uses the @Ord k@ instance to provide fast insertion,
|
||||
deletion and lookup. This implementation is based on Ralf Hinze's
|
||||
<http://citeseer.ist.psu.edu/hinze01simple.html A Simple Implementation Technique for Priority Search Queues>.
|
||||
Hence, it is similar to the
|
||||
<http://hackage.haskell.org/package/PSQueue PSQueue> library, although it is
|
||||
considerably faster and provides a slightly different API.
|
||||
.
|
||||
* @IntPSQ p v@ is a far more efficient implementation. It fixes the key type
|
||||
to @Int@ and uses a <http://en.wikipedia.org/wiki/Radix_tree radix tree>
|
||||
(like @IntMap@) with an additional min-heap property.
|
||||
.
|
||||
* @HashPSQ k p v@ is a fairly straightforward extension of @IntPSQ@: it
|
||||
simply uses the keys' hashes as indices in the @IntPSQ@. If there are any
|
||||
hash collisions, it uses an @OrdPSQ@ to resolve those. The performance of
|
||||
this implementation is comparable to that of @IntPSQ@, but it is more widely
|
||||
applicable since the keys are not restricted to @Int@, but rather to any
|
||||
@Hashable@ datatype.
|
||||
.
|
||||
Each of the three implementations provides the same API, so they can be used
|
||||
interchangeably. The benchmarks show how they perform relative to one
|
||||
another, and also compared to the other Priority Search Queue
|
||||
implementations on Hackage:
|
||||
<http://hackage.haskell.org/package/PSQueue PSQueue>
|
||||
and
|
||||
<http://hackage.haskell.org/package/fingertree-psqueue fingertree-psqueue>.

|
||||
.
|
||||
Typical applications of Priority Search Queues include:
|
||||
.
|
||||
* Caches, and more specifically LRU Caches;
|
||||
.
|
||||
* Schedulers;
|
||||
.
|
||||
* Pathfinding algorithms, such as Dijkstra's and A*.
