Heuristic best-found: the calculator uses deterministic best-fit decreasing. It includes kerf between adjacent pieces and reserves another kerf before a reusable terminal offcut.
The one-dimensional model
Why the last kerf is different
Adjacent finished parts need a kerf between them. The last finished part can use the existing end of the stock, so it does not automatically need another kerf to fit. If you want to separate and save the terminal remainder, however, that offcut loses one more blade width.
The calculator uses deterministic best-fit decreasing: longer parts are placed first, then each goes into the board that leaves the smallest valid remainder. It is a fast, practical heuristic rather than proof of the fewest possible boards for every large job.
