Skip List vs. Binary Search Tree
...Trees" (2014) have to say:
with 128 threads, our algorithm outperforms Java’s non-blocking skiplist
by 13% to 156%, the lock-based AVL tree of Bronson et al. by 63% to 224%, and a RBT that uses software transactional memory (STM) by 13 to 134 times
EDIT to add: Pugh's lock-based skip list,...

If you had to define every possible combination of flags (i...
What's the difference between a method and a function?

In this case, functions would be analogous to static methods and methods would have the same meaning. For 2), you should add that a method is able to operate on the private instance (member) data decl...
