The Container Loading Problem consists of packing boxes of similar sizes into available Containers in such a way to optimize an
objective function. In this paper we are going to apply the concept of Permutation Block Algorithm (PBA) in the wall layer approach
for the Load Optimization of Equal Dimension Boxes in the Container Loading Problem. The load is filled in the vehicle by means of
two methods like by top sides only or by any sides possible. The main objective of this paper deals with the increased use of space
while filling loads into the container.
