Answer :

Local maxima: A local maxima as opposed to a goal maximum is a peak that is lower that the highest peak in the state space. Once a local maxima is reached the algorithm will halt even though the solution may be far from satisfactory. 

Plateaux: A plateaux is an area of the state space where the evaluation fn is essentially flat. The search will conduct a random walk.
