Islands<br />

If we represent a given or computed value of vertices / lines as a height of<br />

vertices / lines and we immerse the network into a water up to selected level<br />

we get islands. Varying the level we get different islands. Islands are very<br />

general and efficient approach to determine the ’important’ subnetworks in<br />

a given network.<br />

We developed very efficient algorithms to determine the islands hierarchy<br />

and to list all the islands of selected sizes.<br />
