示例1: stochastic_greedy_partition
/*
* Procedure will be following:
* 1) in random sequential order, each node is moved to its neighbor module that results in the largest gain of the map eq.
* If no move results in a gain of the map equation, the node stays in its original module.
* 2) repeated 1) procedure, each time in a new random sequential order, until no move generates a gain of the map EQ.
*
* The 1) procedure is implemented in Network::move() function.
