Subject [jira] Updated: (STDCXX-138) algorithms complexity tests not strict enough
Date Mon, 05 Jun 2006 19:44:43 GMT
     [ http://issues.apache.org/jira/browse/STDCXX-138?page=all ]

Martin Sebor updated STDCXX-138:
--------------------------------

    Fix Version: 4.2
                     (was: 4.1.4)

> algorithms complexity tests not strict enough

>          Key: STDCXX-138
>          URL: http://issues.apache.org/jira/browse/STDCXX-138
>      Project: C++ Standard Library
>         Type: Improvement

>   Components: Tests
>     Versions: 4.1.3
>  Environment: all
>     Reporter: Anton Pevtsov
>     Priority: Minor
>      Fix For: 4.2

> Affects tests for sort, stable_sort, partial_sort, partial_sort_copy, nth_element, etc
algorithms where the complexity is O(f(N)), where N is the length of the test sequence, f(N)
- some function of N: log N, N log N, N. 
> It is necessary to investigate each algorithm to find the worst case for it and use the
complexity on this worst sequence as the upper bound in tests. Currently "magic" coefficients
are used.
