Detailed Description

Seed Finder for the electromagnetic algorithm.

The seed finder mosule finds the center of the em cluster by comparing the energy values of the cells The naming and the greater or grater or equal signs are shown in the table below:

up(N-1)>= up(N)> up(N+1)>
N-1 >= N N+1 >
dn(N-1)>= dn(N)>= dn(N+1)>
