Atlas+
ALGORITHM
DESCRIPTION
The following section describes the changes in the
Atlas
algorithm that improve its accuracy. The
improvement is based on the large value of the
local
clustering coefficient
. After that, properties of the
new algorithm,
Atlas
+, are analyzed, and according
to them, two versions of
Atlas
+ are suggested.
The tree construction phase of
Atlas
+ is taken
from the
Atlas
algorithm as is.
K
most popular
vertices are selected as starting vertices, but the
breadth-first search with random tie-break is used as
edge selection strategy. BFS with random tie-break
has been selected because it allows isolated tree
construction.
