WebThe comparative evaluation of the efficiency of the two cylinder packing algorithms, CPA-MinOSA and CPA-MaxNSA, was based on their execution time to solve the test instances. The results obtained are shown in Fig. 9. As expected, CPA-MinOSA expends considerably more time to reach the final solution than CPA-MaxNSA.

Solve these exercise … In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles. Generalisations can be made to higher dimensions – this is called sph…
