Detailed Description

template<bool Stable, typename ValueType, typename Comparator = std::less<ValueType>>
class tlx::LoserTreePointer< Stable, ValueType, Comparator >

Guarded loser tree, using pointers to the elements instead of copying them into the tree nodes.

Unstable specialization of LoserTreeCopyBase.

Guarding is done explicitly through one flag sup per element, inf is not needed due to a better initialization routine. This is a well-performing variant.
