comparisons between slicing and non-slicing approach of vlsi layout floor planning

Slicing representation has some advantages such as smaller encoding cost and solution space bringing faster runtime for packing. Furthermore it is flexible to deal with hard, preplaced, soft and rectilinear blocks. However in real designs optimal solution might not be in the solution space of slicing structure. While with non-slicing representation optimal solution might be achieved but it needs more evaluating runtime for packing then slicing approach.
