An example that compares the features of combo1 and combo2 score functions. (a) An intermediate layout of CCB-grid layout algorithm. In this layout, all six nodes have the same attribute. (b) The next candidate layout that is generated from (a) by moving node v_f below node v_d. Combo scores of (a) and (b) are the same with combo1 score function. Instead, the combo score of (b) will be better than (a) with combo2 score function.
