* computing the longest increasing subsequence of .claim_order values.
*
* This algorithm is optimal in generating the least amount of reorder operations
* possible.
*
* Proof:
* We know that, given a set of reordering operations, the nodes that do not move
* always form an increasing subsequence, since they do not move among each other
* meaning that they must be already ordered among each other. Thus, the maximal
* set of nodes that do not move form a longest increasing subsequence.
