Dear all,

there is a new entry by Walter Guttmann:

Relational Disjoint-Set Forests

We give a simple relation-algebraic semantics of read and write operations on
associative arrays. The array operations seamlessly integrate with assignments
in the Hoare-logic library. Using relation algebras and Kleene algebras we
verify the correctness of an array-based implementation of disjoint-set forests
with a naive union operation and a find operation with path compression.

Enjoy,
René
