Efficient Utility Functions for Ceteris Paribus Preferences

Ceteris paribus (other things being equal) preference provides a convenient means for stating constraints on numeric utility functions, but direct constructions of numerical utility representations from such statements have exponential worstcase cost. This paper describes more efficient constructions that combine analysis of utility independence with constraintbased search.
