Description:
Priority Search Queue; profiling libraries
A /priority search queue/ efficiently supports the opperations of both a search tree and a priority queue. A 'Binding' is a product of a key and a priority. Bindings can be inserted, deleted, modified and queried in logarithmic time, and the binding with the least priority can be retrieved in constant time. A queue can be built from a list of bindings, sorted by keys, in linear time. . This package contains the libraries compiled with profiling enabled.
