Reviewer 1:
For instance, still in the context of task allocation, this recent work http://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1004273 (which I do recommend to include as reference) successfully evolved a task-allocation-like collective behaviour where individuals seem not to have access to a stimulus estimate (for instance, robots that are dropping objects from the top of the slopes do not have an idea on the state of the cache, but still manage to switch between tasks in an effective way).
Besides the above work, the related work section could be extended to include more recent works done in swarm robotics on task allocations. Example are:
