Description
gbTrace = n -- set the tracing level for
the engine of Macaulay2 to level
n. Meaningful values of
n for typical users 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.
