... Since each perfect family of hash functions has size O(log n) 2 O(k) , the overall time complexity of the algorithm is O(2 5k kn 2 log 2 n) 4 O(k) . 5. Conclusion This paper was concerned with two ... Voir le document complet

... ² 2 (t) = u then ² 1 (e 1 )↓ R = Symb(u) = f 1 and ² 2 (e 2 )↓ R = Symb(u) = f 2 . Since every ground term has an unique head symbol and f 1 6= f 2 , ² 1 (e 1 )↓ R ∧ ² 2 (e 2 )↓ R = ⊥. 3 Optimizations An optimization is ... Voir le document complet
