Using hammock graphs to eliminate nonstructured branch statements
The detection of parallelism is based on the dependence analysis of the program. One of the key problems is to partition the program into independent subtasks in the presence of control statements (MIMD). In t...

Auto-Correlations and New Bounds on the Nonlinearity of Boolean Functions
It is a well known fact that the nonlinearity of a function f on the n-dimensional vector space V n is bounded from above by 2n−1 − 21/2n−1. In cryptographic practice, nonlinear functions are usua...

Many-to-one packet routing via matchings
In this paper we study the packet routing problem under the matching model proposed by Alon, Chung and Graham [1]. We extend the model to allow more than one packet per origin and destination node. We give tig...
