Complexity of terms, superpositions, and generalized hypersubstitutions

In this paper, we consider the four useful measurements of the complexity of a term, called the maximum depth, the minimum depth, the variable count, and the operation count. We construct a formula for the complexity of the superposition Sm (s, t1, ..., tm) in terms of complexity of the inputs s, t1...
