Software Design III (CS 340)
Note: For this assignment only, I am relaxing the late-policy rules. Assignments can be handed in without penalty until 9:00 PM, Friday, 16 May 2014 (the end of exam period). Assignments will not be accepted after that point in time.
This assignment will have you solve a well-known problem concerning the “proximity” of actors, measured in terms of whether they have co-starred together, or are connected more indirectly. Made famous as the “Kevin Bacon Number,” the measure works this way: Kevin Bacon has a proximity of 0 to himself. Kevin Bacon has a proximity of 1 to Donald Sutherland, since they co-starred together in Animal House. Kevin Bacon has a proximity of 2 to Daniel Radcliffe, since they never actually co-starred together, but Kevin Bacon co-starred with Helena Bonham Carter in Novocaine, and Helena Bonham Carter co-starred with Daniel Radcliffe in Harry Potter and the Deathly Hallows. More information can be found at The Oracle of Bacon:
http://oracleofbacon.org/
Your code will provide this sort of functionality, allowing a user to read in a database file of actors and their roles, then find a set of distinct shortest paths between those actors (if any such exist). Up to 10 different, disjoint paths can be found at a time (where “disjoint” here means that they have no actors in common, either than the start and end actors in the path; we do not worry about whether or not the paths have some movies in common).
Another note: To help answer questions about what the code should be doing, I have posted some short video demos of it running, with some more description.
http://screencast.com/t/GSMgo6iq62mz http://screencast.com/t/sY37l0MU49a
(a) (10 points) Your first job is to implement the Grapher() constructor. When the user chooses an input text-file, this constructor is called, taking the name of the file as an input, along with a reference to a JTextArea for output as in some prior assignments. The constructor should:
• Read in the text-file chosen by the user. Each line will consist of an actor’s name, followed by the ‘|’ character, followed by a movie (with date, so remakes and similar things are not confused). The set of downloads includes one small file for testing, and two larger files, consisting of all the data for films taken from IMDB (excluding actors/films that have irregular characters in their names), and the same data, restricted to the period starting in 2000, available for download and testing online:
1
http://cs.uwlax.edu/~mallen/courses/cs340/baconInputs.zip
• You need to store the data into whatever structures you need; for the remainder of the assignment, you will want to be able to look up all the movies that any actor starred in, as well as all the actors that starred in any movie. You may want to use, for instance, a pair of hash-maps here, but that is up to you.
• When the data is finished parsing, you should display the number of actors and number of movies stored in the input file, putting that information into the output text-area. (See the video and supplied sample runs of the program to see the format required.)
Note: For the large input files, you may find it necessary to increase the heap space given to the JVM. This is most easily done by adding the necessary arguments when running the compiled program from the command line. The first video linked above covers the basic command needed. For more information, see:
http://preview.tinyurl.com/mwe4e39
(b) (20 points) You also need to fill in the method that finds the shortest path from one actor to another in the data. The best way to implement this is to use something like the shortest-path search seen in the text and in class for graphs. Your search should start with the initial actor, and then see if the second actor appears in any films with them; if so, the path length is 1. If not, the search will need to take all of the actors who appear in the films with the first actor, and see if the second one appears in any films with any of them, and so forth. When a path is found, you should report back to the user the length of that path, along with the movies and other actors involved. (Again, see the videos and sample runs for format.)
Note 01: Your code will need to deal with cases where there are no paths between actors (it can sometimes happen for very obscure individuals), as well as dealing with cases where the person entered is not in the database (due to a misspelling or other issue).
Note 02: In class, we looked at graph search in an explicit form. That is, the data being searched was placed into a complete graph of nodes, and then a search was performed. For this assignment, you can use the same basic idea of the breadth-first search, but you probably do not want to build the entire graph. Particularly on large data-sets, this can be extremely slow, since it will involve building a graph out of every individual in the database, when the search will really only need to involve some small subset of individuals in order to find a shortest path from one to another. You are strongly advised to think about how to implement the search you need without explicitly building the entire graph of individuals first.
(c) (10 points) To finish the project, you should add code so that, if the user enters some value n greater than 1 in the box next to the path-search button, your program returns n distinct paths, shortest to longest, between the two actors. Each path should be disjoint in the sense that no actor (other than the two we are searching for) appears in more than one of those paths, so we have n different ways to get from the first actor to the second. Your code should limit the number searched for to a maximum of 10; if a user enters a value greater than 10, you should politely ignore them, and return 10 paths instead. You will also need to deal with cases where there are less than n paths possible, even under the cap. (Again, the videos and the sample runs provided show the sort of behavior expected of your program.)
2
(d) When you are done, submit your work on the class Moodle site. You should submit an archived folder containing just your source code.
https://moodle.cs.uwlax.edu/course/view.php?id=14
Coding conventions: Each step of the program has a points total, given above. For full points, you should complete all those components, and observe the basic coding conventions as follows:
• Comments should appear at the start of any code-file you write or change, with your name, the date of your work, and a short explanation of what the code does.
• Each method should be preceded by a blank line, followed by at least one line of comments explaining what the method does.
• Methods should be private if possible, and public only if necessary. • Class variables should be local to methods if possible, and should only appear as global
variables if they appear in more than one method of the class. • Unless absolutely necessary, global instance variables should be private. • Code can be broken up by blank lines, but keep this to a low level. There should be no more
than a single blank line separating pieces of code. Within a line of code, white space should not be too wide, for clarity.
• Code should be properly indented and separated into lines. • Basic naming conventions should be followed: variables should begin with a lower-case letter,
while classes begin in upper case; method names (other than constructors) should also start in lower-case.
