Hi all,

Is cube pruning (see http://www.aclweb.org/anthology/P/P07/P07-1019.pdf)
supported by moses out of the box?

The search-algortihm option's description suggests that it is:
-search-algorithm: Which search algorithm to use. 0=normal stack, 1=cube
pruning, 2=cube growing, 4=stack with batched lm requests (default = 0)

and despite the SearchAlgorithm enum in moses/TypeDef.h having a slot
for it:
enum SearchAlgorithm {
...
,CubeGrowing = 2
...
};

the Search::CreateSearch() method does not seem to support this choice:
...
case CubeGrowing:
return NULL;
....

Using "-search-algorithm 2" results in an instant seg fault. I use moses
checked out of github.

Many thanks,
David
