If c is a member of is, then vm(c) = i(c) Let m, or u, i , be a structure of cpdl, vm is a classical valuation (for cpdl) if and only if it is a function whose domain is is rs fm and which meets the following conditions: )f be a member of rs, then vm(cid:523) (cid:524) = i(cid:523) (cid:524) Let be a member of rs, let ad(cid:523) (cid:524) = 1 and let c be a member of is. vm(cid:523) c) = t iff vm(c) is a member of vm(cid:523) (cid:524) Let be a member of rs, let ad(cid:523) (cid:524) = n (where n > 1) and let c1, , cn be. Vm( c1, cn) = t iff vm(c1), vm(cn) is a member of vm(cid:523) (cid:524) occurrences of members of is. Then, for each and for each in fm, Relation of a structure to a formula or set of formulas: Properties of a formula or a set of formulas.

9. Finally, you should write a program MontrealMaps which will suggest a path to go along the metro to get from one place to another. The only required method for MontrealMaps is a main method but of course you are allowed to write others. Your program should do the following. For any library methods that you use, make sure that you are properly importing things and handling any exceptions they may throw. (10 points) • Using an appropriate library method, you should create a Subway System object. If this method fails to initialize, you should print the message Error, not enough funding. • Use a Scanner and print statements to read the current x and y position of the user. • Use a Scanner and print statements to read the x and y position that the user wants to go to. . Find the nearest Metro Station to both the start position of the user and his final destination. • If the 2 metro stations have the same name (i.e. are the same metro station) then print It is fastest to walk there. • Otherwise, call the method findPath from the previous part to find a path from these 2 metro stations. . If the method returns null, then print Sorry, there is no path on the metro, you'll have to walk • Otherwise, print the path using the metro using the method printPath defined in the MapUtilities class in the appendix.
