The important part of a cooperative search is that results are exchanged. In the
case of the teamwork method these results are facts selected by the
referees and integrated into the search state of the best expert of
the previous working period. In the picture we can see the effect of this
integration: The best experts jumps down deeper into the search space and comes
nearer to a solution.
Note that the position the best expert is at now may not be reachable by him
without the help of the other experts it just got. So this is an example for
a behaviour that can only be achieved by a team and not by any team member
alone.
But this is not the only such effect. This link
will take you to the situation at the end of a team meeting.
