Detailed Description
These are some common datastructures used in the implementation of Gecode. Maybe they can be also useful to others.In order to use them, one needs to include the appropriate header-file as described in the class and function documentation.

Default choice of values for the linear congruential generator. While this pseudo-random number generator is not a good source of randomness, it is still an acceptable choice for many applications. The choice of values is taken from D. E. Knuth, The Art of Computer Programming, Vol 2, Seminumerical Algorithms, 3rd edition. Requires #include "gecode/support/random.hh"

Insertion sort. Sorts by insertion the n first elements of array x according to the order lt as instance of class LessThan. The class LessThan must implement the single member function bool operator()(const Type&, const Type&) The algorithm is largely based on the following book: Robert Sedgewick, Algorithms in C++, 3rd edition, 1998, Addison Wesley. Requires #include "gecode/support/sort.hh"

Quicksort. Sorts with quicksort the n first elements of array x according to the order lt as instance of class LessThan. The class LessThan must implement the single member function bool operator()(const Type&, const Type&) The algorithm is largely based on the following book: Robert Sedgewick, Algorithms in C++, 3rd edition, 1998, Addison Wesley.
