Detailed Description

  template<typename _Tp, typename _Compare>
class __gnu_parallel::_LoserTreeUnguardedBase< _Tp, _Compare >"Base class for unguarded _LoserTree implementation. The whole element is copied into the tree structure.

No guarding is done, therefore not a single input sequence must run empty. Unused __sequence heads are marked with a sentinel which is > all elements that are to be merged.

This is a very fast variant.
