CONTENTS OF THESE FILES

STRONG COMPONENTS ALGORITHMS
gscc.h,gscc.c, gscc1.c - path-based algorithm (Gabow)
kscc.h, kscc.c, kscc1.c - multi-pass algorithm (Kosaraju-Sharir)
tscc.h,tscc.c,tscc1.c,tscc2.c -Lowpoint algorithm (Tarjan)

SUPPORTING DATA STRUCTURES
digraph.h,digraph.c
intarray.h
stack.h
util.h

GRAPH GENERATORS
gen.h, random.h
acyclic.c - random acyclic digraphs on a fixed number of vertices
any.c - random digraphs on a fixed number of vertices
dense.c
       random dense digraphs (having a fixed fraction 1/p of #edges of
       the complete digraph with the same number of vertices) in either
       expected (#edges) or exact version
grid2d.c
grid3d.c
       2D & 3D grids each in 8 flavors:
          wraparound VS no wraparound,
          oriented VS expected,
          permuted names VS no permuted names.
hcube.c - randomly-oriented hypercubes in either expected or oriented version
thard.c - two hard families for LOWPOINT

MAIN ROUTINES
test_acy.c,test_any.c,test_den.c,test_gri.c,test_hcu.c,test_tha.c
   generates graphs of the appropriate family and prints out timing statistics
   for each of the 3 SC algorithms

tester.h,tester.c- times all 3 SC algorithms on the family
