  abstract =     "We present an analysis of the temporal evolution of a
                 scientific coauthorship network, the genetic
                 programming network. We find evidence that the network
                 grows according to preferential attachment, with a
                 slightly sublinear rate. We empirically find how a
                 giant component forms and develops, and we characterise
                 the network by several other time-varying quantities:
                 the mean degree, the clustering coefficient, the
                 average path length, and the degree distribution. We
                 find that the first three statistics increase over time
                 in the growing network; the degree distribution tends
                 to stabilise toward an exponentially truncated
                 power-law. We finally suggest an effective network
                 interpretation that takes into account the aging of
                 collaboration relationships.",
