8 deftemplate (deftemplate (slot-1). (slot-n) ) (deftemplate take-sticks (slot how-many) (slot for-remainder) ) Sample: (take-sticks (how-many 1) (for-remainder 1) )

10 Math operators  (+  (-  (*  (/ ( ?size) (+ (* 6 7) 3) Sample:

11 Logical operators  (and  (or  (not &|~&|~ (or (not (integerp ?choice)) ( ?choice 3) (> ?choice ?size)) (player-select ?player&~c&~h) Sample:

16 Example  Rule Move-Directly IF The goal is to move block ?upper on top of block ?lower AND Block ?upper is the top block in its stack AND Block ?lower is the top block in its stack THEN Move block ?upper on top of block ?lower  Rule Clear-Upper-Block IF The goal is to move block ?x AND Block ?x is not the top block in its stack AND Block ?above is on top of block ?x THEN The goal is to move block ?above to the floor

17 Example  Rule Clear-Lower-Block IF The goal is to move another block on top of block ?x AND Block ?x is not the top block in its stack AND Block ?above is on top of block ?x THEN The goal is to move block ?above to the floor  Rule Move-To-Floor IF The goal is to move block ?upper on top of the floor AND Block ?upper is the top block in its stack THEN Move block ?upper on top of the floor

18 Example:  Facts   (on-top-of (upper nothing)(lower A))  (on-top-of (upper A)(lower B))  (on-top-of (upper B)(lower C))  (on-top-of (upper C)(lower floor))  (on-top-of (upper nothing)(lower D))  (on-top-of (upper D)(lower E))  (on-top-of (upper E)(lower F))  (on-top-of (upper F)(lower floor)) (deftemplate on-top-of (slot upper) (slot lower) )

19 Example:  Facts   (block A)  (block B)  (block C)  (block D)  (block E)  (block F)

20 Example:  Facts   (goal (move C)(on-top-of E)) (deftemplate goal (slot move) (slot on-top-of) )

21 Example:  Rules  (defrule Move-Directly ?goal <- (goal (move ?block1)(on-top-of ?block2)) (block ?block1) (block ?block2) (on-top-of (upper nothing)(lower ?block1)) ?stack-1 <- (on-top-of (upper ?block1)(lower ?block3)) ?stack-2 <- (on-top-of (upper nothing)(lower ?block2)) => (retract?goal ?stack-1 ?stack-2) (assert (on-top-of (upper ?block1)(lower ?block2)) (on-top-of (upper nothing)(lower ?block3)) ) (printout t ?block1 " moved on top of " ?block2 "." crlf) )  Rule Move-Directly IF The goal is to move block ?upper on yop of block ?lower AND Block ?upper is the top block in its stack AND Block ?lower is the top block in its stack THEN Move block ?upper on top of block ?lower

22 Example:  Rules  (defrule Clear-Upper-Block (goal (move ?block1)) (block ?block1) (on-top-of (upper ?block2)(lower ?block1)) (block ?block2) => (assert (goal (move ?block2)(on-top-of floor)) )  Rule Clear-Upper-Block IF The goal is to move block ?x AND Block ?x is not the top block in its stack AND Block ?above is on top of block ?x THEN The goal is to move block ?above to the floor

23 Example:  Rules  (defrule Clear-Lower-Block (goal (on-top-of ?block1)) (block ?block1) (on-top-of (upper ?block2)(lower ?block1)) => (assert (goal (move ?block2)(on-top-of floor)) )  Rule Clear-Lower-Block IF The goal is to move another block on top of block ?x AND Block ?x is not the top block in its stack AND Block ?above is on top of block ?x THEN The goal is to move block ?above to the floor

24 Example:  Rules  (defrule move-to-floor ?goal <- (goal (move ?block1)(on-top-of floor)) (block ?block1) (on-top-of (upper nothing)(lower ?block1)) ?stack <- (on-top-of (upper ?block1)(lower ?block2)) => (retract ?goal ?stack) (assert (on-top-of (upper ?block1)(lower floor)) (on-top-of (upper nothing)(lower ?block2)) ) (printout t ?block1 " moved to floor." crlf) )  Rule Move-To-Floor IF The goal is to move block ?upper on top of the floor AND Block ?upper is the top block in its stack THEN Move block ?upper on top of the floor
