The bipartite network consists of donor nodes (red) with outgoing links
acceptor nodes (blue) with incoming links (nodes without links are
grey). At each step two randomly
nodes merge. If the two nodes are of the same type, the links add up to
one large node. If the nodes are of different type, links annihilate
until the smaller node vanishes. This is interpreted as an energy burst
visualized with a flash-size proportional to the burst.
The size of the bursts is power-law distributed.
When pressing "Initialize" the network restarts at the vacuum state
without any links.
Links are created by small excitations every step when two randomly
chosen nodes get respectively one extra unit blue or red by addition of
a link with a blue and a red end. The number of links
between two nodes can be larger than one and can be estimated by the
color of the plotted link. The more links
a node has, the closer to the center of the network the
node is plotted.
way to interpret this merging model of a bipartite network is to
consider the nodes as sunspots and the links as the associated magnetic
field-lines in the solar atmosphere. Two sunspots of the same polarity
merge to a larger sunspot and when two sunspots of different polarity
merge the magnetic field-lines annihilate and energy is released. The
size of these energy bursts have been measured two be power-law
