Space-Time Tradeoffs in Structured Programming: An Improved Combinatorial Embedding Theorem.
Abstract
Let G and G* be programs represented by directed graphs. We define a relation < or = sub S, T between G and G* that formalizes the notion of G* simulating G with S-fold loss of space efficiency and T-fold loss of time efficiency, and prove that if G < or = sub S, T G*, where G has n statements and G* is structured, then in the worst case T + log sub 2 (log sub 2 S) > or = log sub 2 (n) + 0(log sub 2(log sub 2n)).
