In such a network, a sink node desires to compute with zero error a {\\em target function}, of which the inputs are generated at multiple source nodes. The edges in the network are assumed to be error-free and have limited capacity. The nodes in the network are assumed to have unbounded computing capability and be able to perform network coding. The {\\em computing rate} of a network code that can compute the target function over the network is the average number of times that the target fu","authors_text":"Congduan Li, Raymond W.
