Both Sequence and Context Unification generalize the same problem: Word Unification. Besides that, Sequence Unification solves equations between unranked terms involving sequence ...
We show that stratified context unification, which is one of the most expressive fragments of context unification known to be decidable, is equivalent to the satisfiability proble...
Linear Second-Order Unification and Context Unification are closely related problems. However, their equivalence was never formally proved. Context unification is a restriction of ...
Abstract. Context unification (CU) is the open problem of solving context equations for trees. We distinguish a new decidable variant of CU? well-nested CU ? and present a new unif...
