We present a collection of new techniques for designing
and analyzing e cient external-memory algorithms for
graph problems and illustrate how these techniques can
be applied to a wide variety of speci c problems. Our
results include:
Proximate-neighboring. We present a simple
method for deriving external-memory lower bounds
via reductions from a problem we call the proxi-
mate neighbors" problem. We use this technique to
derive non-trivial lower bounds for such problems
as list ranking, expression tree evaluation, and con-
