Next, we apply a combination of the proposed cross-based scheduling
method and grouping-based droplet-based manipulation to the routing
plan. The results are shown in Table 3.5. Compared to the results shown in
Table 3.4, droplet-movement concurrency is significantly improved. Half
of the cycles now contain the concurrent manipulation of more than two
droplets. In some cycles, even four droplets are moved simultaneously. As a
result, only 34 cycles are required for this routing plan, which is only 57% of
the time required for one-at-a-time droplet, and 64% of the time required if
droplet grouping is carried out without route scheduling.
Note that the completion time obtained using the proposed droplet-
manipulation method is slightly more than that for the direct-addressing
