ABSTRACT
A runtime analysis is made of a previously published algorithm for polynomial composition. The relationship between this composition algorithm and Sablonnie`re's algorithm is explored. This composition algorithm is then made optimal aby first performing a change of basis.

REVIEW
"Andrew Timothy Thornton : Reviewer"
While it is generally computationally more efficient for surface
modeling systems to work with composed polynomials (such as
F˙G
), there are inevitably occasions when it is necessary
