Simulated annealing may be useful when we try to optimize the position
of components. For toporouters we have the concept of cuts and cut
capacity (distance of adjacent terminals in the constrained delaunay
triangulation, space occupied by traces). If there is unused capacity,
we may try to move components together to reduce PCB area and trace
length.
