Subject: [Caml-list] [CAML]:: efficient data structure for storing and searching int list list

Dear all:


I have an int list list, whose name is LL


and I need to frequently decide whether a particular int list, whose name is L, is a sublist of an element of LL.


Is there any efficent data structure to do this?


At the mean time, I store LL as (int, bool) Hashtbl.t list, that is, each element of LL is stored as a hash table.


So searching L in LL is reduce to decide whether there exist an element of LL, such every element of L hit in this element.


At the mean time, the space is not a big problem, but the run time overhead is major concern,


So if there exist any more faster data structure?


Thank you


Shen
