n1 = the number of distinct operators

n2 = the number of distinct operands

N1 = the total number of operators

N2 = the total number of operands

From these numbers, five measures are derived:

Program length

N= N1 + N2

Program vocabulary

n= n1 + n2

Volume

V= N * (LOG2 n)

Difficulty

D= (n1/2) * (N2/n2)

Effort

E= D * V
