Abstract: | In this paper networks that optimize a combined measure of local and global synchronizability are evolved. It is shown that
for low coupling improvements in the local synchronizability dominate network evolution. This leads to an expressed grouping
of elements with similar native frequency into cliques, allowing for an early onset of synchronization, but rendering full
synchronization hard to achieve. In contrast, for large coupling the network evolution is governed by improvements towards
full synchronization, preventing any expressed community structure. Such networks exhibit strong coupling between dissimilar
oscillators. Albeit a rapid transition to full synchronization is achieved, the onset of synchronization is delayed in comparison
to the first type of networks. The paper illustrates that an early onset of synchronization (which relates to clustering)
and global synchronization are conflicting demands on network topology. |
