sagbiDegree -- The current degree of the subalgebra bases computation

Synopsis

• Usage:

  result = sagbiDegree SB

• Inputs:
  • SB, a SAGBIBasis,
• Outputs:
  • result, an integer, the current degree of computation in SB.

Description

i1 : R = QQ[x,y];

i2 : S = subring{x+y,x*y,x*y^2,x*y^5+y};

i3 : T = sagbiBasis S;

i4 : sagbiDegree T

o4 = -1

i5 : sagbiDegree sagbi(S,Limit=>5)

o5 = 6

i6 : sagbiDegree sagbi(S,Limit=>20)

o6 = 7

i7 : isSAGBI(S,UseSubringGens=>false)

o7 = true
