Complexities for generalized models of self-assembly
In this paper, we extend Rothemund and Winfree's examination of the tile complexity of tile self-assembly [6]. They provided a lower bound of ( log N log log N ) on the tile ...

Threshold arrangements and the knapsack problem
We show that a combinatorial question which has been studied in connection with lower bounds for the knapsack problem by Brimkov and Dantchev (2001) is related to threshold graphs...

Pseudocodeword weights for non-binary LDPC codes
Abstract-- Pseudocodewords of q-ary LDPC codes are examined and the weight of a pseudocodeword on the q-ary symmetric channel is defined. The weight definition of a pseudocodeword ...

Optimal prices for finite capacity queueing systems
We prove a lower bound on the optimal price for a fairly large class of blocking systems with general arrival and service processes, determine optimal price expressions for M/M/1/...
