Construction heuristics also have the concept of a step scope and a move 
scope. If you put logging on DEBUG, you 'll see its steps. With logging 
on TRACE, you 'll see its steps and moves.
Note: only since 5.4 the construction heuristics actually use moves.

In 5.4 and earlier, the "old" selector was local search only and very 
limited.
 From 5.5.0.Beta1 (soon to be released), a much more flexible new 
selector architecture has been written, which is already working for 
local search.
After the new selector docs are done (probably for 5.5.0.Beta2), I 'll 
be looking into applying the new selector architecture to construction 
heuristics too. That will make them much more configurable and scalable.
