ABSTRACT:
Objects are placed in a rectangle and their coordinates of the objects and are adjusted to establish a substantially uniform density of objects in the rectangle. The evaluation of coordinates is performed by placing the wires between cells coordinates and adjusting the cell coordinates to connect the cells to the wires. The substantially uniform density is achieved by dividing the rectangle into first and second rectangles having equal free areas and into third and fourth rectangles having equal areas of objects. The coordinates of the objects are adjusted based on boundaries between the first and second rectangles and between the third and fourth rectangles.
