Abstract
In this paper we motivate and present a new and improved transformation system for general E-unification. It can be seen as a modification of the original transformation system by Gallier and Snyder refined by ordinary unification and basic paramodulation. We present a short proof of completeness. Besides completeness we can also show an important property of the transformation system which is not known for the original system: independence of the selection rule. This motivates the abstraction of transformation sequences to equational proof trees thus obtaining static proof objects which facilitates finding further refinements of the procedure.
