Using the zip codes, the seeds can be sorted on + each snarl tree structure separately. Seeds along a chain are sorted to be ordered along a + chain, and seeds in a snarl are sorted by the child of the snarl that they are on. The seeds + get sorted using a radix-like sort on each structure at each depth of the snarl tree, starting + with the root and moving down. + "Intervals" of seeds in the sort order are used to keep track of the location on the snarl + tree. An interval represents a range of seeds that are all on the same snarl tree structure. + After sorting an interval at one depth, sub-intervals representing the children can be found. + So first, the seeds are sorted into connected components and sliced into intervals + representing root-level snarls and chains. Each interval is then sorted to order the seeds + along the snarl or chain, and new intervals are found representing ranges of seeds on the + children. + + Sorting and tree-building are done at the same time, progressively at each structure in the + snarl tree. The order of tree-building is based on a stack of intervals. The algorithm starts + with an interval for each child of the root snarl. An interval is popped from the stack. Any + incomplete snarls or chains that the interval is not a child of must be completed. Then, the + snarl or chain that the interval represents is started in the zip tree, and any relevant + distances are added. Intervals representing the children of the snarl or chain are found and + added to the stack. This repeats until the stack is empty. + + Each snarl and chain in the zip code tree is comprised of the start and end bounds, the + children, and distances between children/bounds. So as each child is added, we will need + to know what came before it in the parent snarl/chain so that we can add the distances. We + also need to remember the ancestors of each snarl and chain as we are building them, so that + we can close each structure properly.
