[Boost-users] Finding the n smallest items in a list

Hi there, I'm searching for a method to find the n smallest numbers in a list of m >> n numbers. The n numbers need to be sorted. m will usually be in the range of 100-1000, n will be 5 or less. So far I'm simply sorting the entire vector, which I assume is not very efficient, as the other m-n items in the container can remain unsorted. Is there a function in Boost that can help me in this situation ? Best Regards, Ruediger
