Query Optimiser Question

I have a question sitting here infront of me :



Describe how cost based query optimisers work and include an explanation as
to how they reduce the solution space and what aspects are compared by the
optimiser.



Its just the solution space i am abit puzzled by.  Does this refer to the
amount of space taken up by solution strategies in the DBMS? If so how does
taking up large amounts of so called solution space lead to problems?



Thanx


Paul
