Summary

The existing algorithm is well-behaved, but extensions to it, from which it can greatly benefit, are already foreseen. The problem is not thoroughly understood and some of the directions it may take depend on discussions and slow exploration of the effects that slight, or at times rather radical, changes make. Section was aimed to show some of the more erratic ideas which either bear potential or possibly be disastrous. Nonetheless, these should motivate discussions and incompletely depict possible ways of going ahead.
