Description
gbTrace = n -- set the tracing level for the
engine to level
n. Meaningful values for the user
n are 0, 1, 2, and 3. Meaningful values for the developers are 4, 5, 8, 10, 11, and 100; the parity also has an effect when the value is at least 5.
The notations used in tracing are :
-
g - a generator reduced to something nonzero and has been added to the basis.
-
m - an S-pair reduced to something nonzero and has been added to the basis.
-
z - an S-pair reduced to zero, and a syzygy has been recorded.
-
u - an S-pair reduced to zero, but the syzygy need not be recorded.
-
o - an S-pair or generator reduced to zero, but no new syzygy occurred.
-
r - an S-pair has been removed.
-
{2} - beginning to reduce the S-pairs of degree 2.
-
(7) - 7 more S-pairs need to be reduced.
-
(8,9) - 9 S-pairs, 8 predicted basis elements (gb(...,Hilbert=>...))
-
. - a minor has been computed, or something has happened while computing a resolution.
