Ordering-algorithm time in the log file
Describes the report of the time used by ordering algorithm of the barrier optimizer.
After the number of nonzeros in the lower triangle of
AAT, CPLEX records the time
required by the ordering algorithm. (The CPLEX barrier optimizer offers
you a choice of several ordering algorithms, explained in Choosing an ordering algorithm.)
This section in the log file indicates which ordering algorithm the
default Automatic setting chose.
