Example 5 with MutableIntCollection

use of org.eclipse.collections.api.collection.primitive.MutableIntCollection in project narchy by automenta.

the class GraphMeter method multicast.

// --------------------------------------------------------------------
/**
 * Performs anti-entropy epidemic multicasting from node 0.
 * As a result the number of nodes that have been reached in cycle i
 * is put into <code>b[i]</code>.
 * The number of cycles performed is determined by <code>b.length</code>.
 * In each cycle each node contacts a random neighbour and exchanges
 * information. The simulation is generational: when a node contacts a neighbor
 * in cycle i, it sees their state as in cycle i-1, besides, all nodes update
 * their state at the same time point, synchronously.
