isDegreeTriplet(Triplet) -- checks if it is a degree triplet

Synopsis

• Function: isDegreeTriplet

• Usage:

  isDegreeTriplet T

• Inputs:
  • T, an instance of the type Triplet, a triplet of degree sequences
• Outputs:
  • a Boolean value, whether it is a degree triplet or not

Description

i1 : T1 = triplet({1,2,3}, {0,2}, {0,2,3})

o1 = {{1, 2, 3}, {0, 2}, {0, 2, 3}}

o1 : Triplet

i2 : isDegreeTriplet(T1)

o2 = true

i3 : T2 = triplet({1,2,3}, {0,2}, {0,1,3})

o3 = {{1, 2, 3}, {0, 2}, {0, 1, 3}}

o3 : Triplet

i4 : isDegreeTriplet(T2)
second and third are underbalanced

o4 = false
