Tasks are categorized into small and large tasks based on the watts requirement.
All the large tasks are packed into offers from agents belonging to power class A and power class B, using BinPacking.
All the small tasks are spread among the offers from agents belonging to power class C and power class D, using FirstFit.

This was done to give a little more room for the large tasks (power intensive) for execution and reduce the possibility of
starvation of power intensive tasks.
