We present a set of experiments in which simulated robots are evolved for the ability to aggregate and move together toward a light target. By developing and using quantitative indexes that capture the structural properties of the emerged formations, we show that evolved individuals display interesting behavioral patterns in which groups of robots act as a single unit. Moreover, evolved groups ...

1 . Throughout this paper, we use the following notation : c•1 , c2 , . . ., X0 , X1 , . . . denote positive absolute constants. We denote the number of elements of the finite set S by BSI . We write ex =exp (x) . We denote the least prime factor of n by p(n) . We write pall n if pain but pa+1 f n . v(n) denotes the number of the distinct prime factors of n, while the number of all the prime fa...

Wait long enough for a bus and two arrive at once. As with buses, so with bronchiectasis scoring systems. In this issue of the European Respiratory Journal MARTINEZ-GARCIA et al. [1] report the development of a ‘‘FACED’’ bronchiectasis prognostic score. This follows the recent publication by CHALMERS et al. [2] of the ‘‘Bronchiectasis Severity Index’’ (BSI). Bronchiectasis is a neglected diseas...
