Center node: "distributed pattern formation in a ring"
  Abstract: Motivated by concerns about diversity in social networks, we consider the following pattern formation problems in rings. Assume $n$ mobile agents are located at the nodes of an $n$-node ring network. Each agent is assigned a colour from the set $\{c_1, c_2, \ldots, c_q \}$. The ring is divided into $k$ contiguous {\em blocks} or neighbourhoods of length $p$. The agents are required to rearrange themselves in a distributed manner to satisfy given diversity requirements: in each block $j$ and for each colour $c_i$, there must be exactly $n_i(j) >0$ agents of colour $c_i$ in block $j$. Agents are assumed to be able to see agents in adjacent blocks, and move to any position in adjacent blocks in one time step. When the number of colours $q=2$, we give an algorithm that terminates in time $N_1/n^*_1 + k + 4$ where $N_1$ is the total number of agents of colour $c_1$ and $n^*_1$ is the minimum number of agents of colour $c_1$ required in any block. When the diversity requirements are the same in every block, our algorithm requires $3k+4$ steps, and is asymptotically optimal. Our algorithm generalizes for an arbitrary number of colours, and terminates in $O(nk)$ steps. We also show how to extend it to achieve arbitrary specific final patterns, provided there is at least one agent of every colour in every pattern.
