Query: Packing circles within circular containers: a new heuristic algorithm
  for the balance constraints case   In this work we propose a heuristic algorithm for the layout optimization for
disks installed in a rotating circular container. This is a unequal circle
packing problem with additional balance constraints. It proved to be an NP-hard
problem, which justifies heuristics methods for its resolution in larger
instances. The main feature of our heuristic is based on the selection of the
next circle to be placed inside the container according to the position of the
system's center of mass. Our approach has been tested on a series of instances
up to 55 circles and compared with the literature. Computational results show
good performance in terms of solution quality and computational time for the
proposed algorithm.
