Base code for conducting a new interview experiment: let the interviewer and the candidate try to come up with and analyze algorithm(s) for generating Voronoi diagrams!
The simple frontend lets the user specify points. Clicking either of the two algorithm buttons
will send the point list up to the server. The server should respond with a Graph data structure
stringified to JSON. The structure contains at a minimum an "edges" property whose data is an array of
line objects, each specified with {x0: x0, y0: y0, x1: x1, y1: y1} to define the line between points (x0, y0) and (x1, y1).
See ui.js for further details.
Included is an old implementation of the classic Fortune's algorithm to check against. The idea is that using a similar interface, the interviewer + candidate should be able to work on algorithm(s) generating the same data. Maybe even work up to an independent implementation of Fortune's Algorithm itself!
This also provides a base framework for more traditional interviews... The interviewer can request working code that is easy to verify, e.g. in 30-60 minutes generate the diagram for two points (see the two-point-problem-statement branch for detailed notes on this) or given a full two hours try to generate the full diagram.
Alternative problems are available too like getting a demonstration of the 4-color theorem or generating splines, and of course there is always the potential to discuss better refactors, improvements, test coverage... Can discuss augmenting the graph structure with the site data or bounding polygon info or other things to facilitate coloring, answering geospatial queries, implementing convex hull, etc. Lots and lots of options.
This project is a maven project.
If you use Eclipse, and have the m2e plugin installed, you can import the voronoi_base project with:
File -> Import -> Maven -> Existing Maven Projects -> Select the Voronoi Base folder
Once that is done you should be able to launch Application.java.
If you want to use the command line only, you can:
git clone https://github.com/Jach/voronoi_base
cd voronoi_base
mvn clean package
Then you can launch the application with
mvn exec:java
and further change-run cycles with mvn compile exec:java, alternatively you can just run the uberjar that was packaged:
java -jar target/voronoi_base-1.0-SNAPSHOT-jar-with-dependencies.jar
