Equivalence of Deterministic Nested Word to Word Transducers
We study the equivalence problem of deterministic nested word to word transducers and show it to be suprisingly robust. Modulo polynomal time reductions, it can be identified with...

Bin Packing with Fixed Number of Bins Revisited
As Bin Packing is NP-hard already for k = 2 bins, it is unlikely to be solvable in polynomial time even if the number of bins is a fixed constant. However, if the sizes of the item...
