CONSTRAINT SATISFACTION-Problem

Suppose you have a bachelors degree in something other than a computing major, something

with no more math than College Algebra, and you want to get a Computer Science degree in six

semesters. You would need to take the following courses:

Math 120, 210, and 215

ICS 140, 141, 232, 240, 311, 340, 365, 372, 440, 460, 462, and 499

For the purposes of this problem, here are the courses and their prerequisites. These are also shown in the graph on the next page.

All of these courses are offered each semester. Suppose you wish to finish these courses within 6 semesters.,numbered 1-6. That is, the domain of each course is the set of semesters in which it can be offered, and the domain of each course is initially set to {1,2,3,4,5,6}.Prune the domains of these courses as much as necessary to make all the prerequisite arcs arc-consistent. Write your answers for the final domains on the lines below.
