This is not a bug as such. Enforced hill-climbing is an incomplete algorithm. The output could be amended to make this clearer; it shouldn't say "unsolvable".

Yes it would be better if incomplete algorithms do not output "Task unsolvable." The warning that no solution was found is enough. This way algorithm configurators such as SMAC can distinguish between unsolvable and no solution.

Make clear that EHC is incomplete. Fixes issue #3.

Original report by Martin Goth (Bitbucket: mgoth, ).
Enforced hill climbing with hadd returns unsolvable on airport/task16.pddl while other planner configurations return a solution:
Expected behaviour: Enforced hill-climbing only returns unsolvable if there exists no solution for the task.
