here is the link to the skip list paper from william pugh:
ftp://ftp.cs.umd.edu/pub/skipLists/skiplists.pdf.

briefly (from the abstract of the above paper):
,----
| Skip lists are a data structure that can be used in place of balanced trees.
| Skip lists use probabilistic balancing rather than strictly enforced balancing
| and as a result the algorithms for insertion and deletion in skip lists are
| much simpler and significantly faster than equivalent algorithms for
| balanced trees.
`----

also, you can google for 'deterministic skip list' for a deterministic
alternatives to the data structure described in the above paper.

kind regards
