This is an example to show you some of the features of the inference engine.

line 54 Qualifications for CS

AND

general_math_level	=	beta

likes	=	programming

likes	=	computer architecture

Then

program	:=	CS

line 103 Your general math level (less specific, will make other rules easier to write)

math_level	=	B1

math_level	=	B2

math_level	=	D

Then

general_math_level	:=	beta

line 120 If you followed astropyhics or artificial intelligence, we know your math is just fine.

previous_program	=	Artificial Intelligence

previous_program	=	Astrophysics

Then

previous_math_level	:=	beta

line 136 Your general math level stays the same if you followed a previous program at the university.

NOT

previous_program	=	none

Then

general_math_level	:=	$previous_math_level
