sagbiLimit -- The current limit of the subalgebra bases computation

Synopsis

• Usage:

  result = sagbiLimit SB

• Inputs:
  • SB, a SAGBIBasis,
• Outputs:
  • result, an integer, the current upper bound on degree of a subalgebra bases computation

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 : sagbiLimit T

o4 = -1

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

o5 = 5

i6 : sagbiLimit sagbi(S,Limit=>30)

o6 = 30
