"Explosive Percolation"

Abstract

A biased link occupation rule discourages the growth of large clusters  
much ahead of others and encourages faster growth of clusters which  
lag behind. The resulting percolation transition, proposed recently,  
is discontinuous, and referred to as 'Explosive percolation'. We will  
discuss the results on a variety of graphs. We also introduce a new  
model with a single parameter alpha, and show that the transition is  
discontinuous for alpha < alpha_c and continuous above. Our model  
might help in understanding the mechanism for this novel transition.
