ER(PolynomialRing,ZZ,List) -- Graded Erdos-Renyi type distribution on monomials over (R,D,L)

Synopsis

• Function: ER

• Usage:

  ER(PolynomialRing,ZZ,List)

• Inputs:
  • R, a polynomial ring, the ring in which monomials are chosen from
  • D, an integer, maximum degree
  • L, a list, of real numbers whose i-th entry is the probability of selecting a monomial of degree i, or of integers whose i-th entry is the number of monomials of degree i in each set
• Outputs:
  • an instance of the type Model, Erdos-Renyi type model
