Lower Bounds for the Relative Greedy Algorithm for Approximating
... The second lower bound is obtained by constructing an instance G k,l which places the instance Gk into a grid. The instance Gk,l consists of an 4k × l grid of terminals where the last terminals of each column have been identified as one terminal. For each column of terminals the graph Gk − Tb − Tc i ...

... where p(X, Y) is a shorthand for {(X, Y)Ip(X, Y) is proved}, and, for any predicate s( X, Y), sj( X, Y) is defined as the set of s tuples which have been proved at the completion of the jth iteration; w is the usual join operator, and + is the set union. Asj is then the set of (possibly) new 8 tuple ...

Hopefully, very simple algorithms are efficient when this ratio is large while iterative algorithms are proved to be efficient for small values of this ratio throu ...
