Subject: Binary Search Tree and Treap Functions bst-assq and treap-put
Date: Sat, 3 Dec 2016 20:42:36 -0500	[thread overview]
Message-ID: <CAHtDYY9ibUs2v6Up66J_ft1mM5S_kAvMZ2fKHHtcLpsq5MdPzg@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 519 bytes --]

I have implemented standard binary search tree lookup and hash-ordered
treap insertion using XLI comparison for lookup and XLI comparison and
FNV-1a hashing of the XLI result for insertion (using the XLI result as the
hash value would result in the worst case for balancing).  I have the
changes available in a local branch and am uncertain what to do with them
now.  I intend to use these functions to make lexically-scoped variable
lookup average case O(log(n)) instead of the current O(n).

Thanks,

Andy Sonnenburg
