Source: Start optimizing in the stripe I have the most successors
Added statistic for number-of-nodes-active-in-X-trees
Nodes ran out of bandwidth too early
Optimize even when currently searching a new parent
Forgot to commit: Added statistic for number-of-nodes-active-in-X-trees
Cleanup
Correct statistic collection
Completely rely on SI messages (dont try to "guess" childs number of succ)
Try not give/drop children to nodes already forwarding in another stripe
Added randomness to getCostliest/Cheapest (if nodes have the same cost/gain)
Refactor/Logs/Comments
Source: Optimize next stripe after dropping one node (to even things out). Request nodes in the stripe with least children
Minor
different weights
