A framework for data structures,al class. Since many data structures cannot be modelled by tree structures in a natural way, such a generalisation to graphs is desirable. Furthermore, the concept of hierarchy in which a node may serve for an arbitrary complex substructure supports a structured view of complex data objects.

An observation concerning the complexity of problems with few solutions and its application to crypds to a ‘yes’ answer — then A is not NP-hard. We apply this result to Cryptography, and show that if our new hypothesis is true then a well designed cryptosystem, whose cracking problem is NP-hard, contains a large subproblem which is not NP-hard.

Our structure is as simple as the one proposed by Brown/Tarjan, but our structure can treat arbitrary sequences of insertions and deletions whilst theirs can only treat non-interacting insertions and deletions.

Optimization is then carried out by graph manipulations. This is sketched by some examples, namely local common subexpression elimination, motion of loop invariant computations, and induction variable elimination.

We will see that this simple structure can efficiently solve the rather difficult problems of multiplying matrices and of constructing minimum spanning trees.
