Rule-Based Languages:
Prolog
Father(abraham, isaac). Male(isaac).
Father(haran, lot). Male(lot).
Father(haran, milcah). Female(milcah).
Father(haran, yiscah). Female(yiscah).
Son(X,Y)  Father(Y,X), Male(X).
Daughter(X,Y)  Father(Y,X), Female(X).
Son(lot, haran)?

Search
 All AI is search
 Game theory
 Problem spaces
 Every problem is a virtual tree of all
possible (successful or unsuccessful)
solutions.
 The trick is to find an efficient search
strategy.
