5.3.1 degBound

Type:
int
Purpose:
The standard basis computation is stopped if the total (weighted) degree exceeds degBound - used in std, slimgb, system("verifyGB",..)
degBound should not be used for a global ordering with inhomogeneous input, if the ordering is not dp or Dp. (Remark: elimination requires always an eliminiation ordering).
Reset this bound by setting degBound to 0.
The exact meaning of "degree" depends on the ring ordering and the command: slimgb uses always the total degree with weights 1, std does so for block orderings, only.
Example:
 
degBound = 7;
option();
==> //options for 'std'-command: degBound
ideal j=std(i);
degBound;
==> 7
degBound = 0; //resets degree bound to infinity
See deg; int; option; std; system.
