• To group the documents in a cluster; clusters centres
are required. The document associate to centre value
is grouped in same cluster. The cluster centres are
chosen by finding the local minima of potential
energy V(x); the potential function of Schrodinger
equation using equation (4)
• The energy maintain as ground state energy; which
value will be 0. The equation is solving for potential
function by adding constant with energy using
equation (3).
