Different worker threads (volunteers) tend to use different sorting algorithm. Personally I use insertion sort, which is a comparison sort. | Different worker threads (volunteers) tend to use different sorting algorithm. Personally I use insertion sort, which is a comparison sort. | ||

However there are some physical optimisation which I made. I collapsed consecutive sorted barcodes into clusters. This is because physically inserting a barcode involves moving all the adjacent barcodes, which takes quite a bit of effort on a rough surface. The two figures below illustrate what I meant: | However there are some physical optimisation which I made. I collapsed consecutive sorted barcodes into clusters.
