gbTrace = n -- set the tracing level for the
engine to level
n. Meaningful values for the user
n are 0, 1, 2, and 3.
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) - there are 8 S-pairs to do in this degree, and 9 more in higher degrees.
- . - a minor has been computed, or something has happened while computing a resolution.
