In the present work, the effect on the physical properties viz. average coordination number, number of constraints, cross-linking density, molecular weight, fraction of floppy modes, mean bond energy, glass transition temperature etc., with the variation in Indium content has been studied theoretically for Ge22Se78-xInx (x=3,6,9,12,15,18,21at.%) glassy alloys. The glass transition temperature and mean bond energy are calculated by using the Tichy-Ticha approach. It has been found that almost all the parameters, studied here, except mean bond energy
