ICFP Contest 2013 Post Mortem

This is a short post mortem about my first participation in an ICFP contest. Overall, it was much fun. I liked the abstract nature of the problem and that the server system worked as described.

The solution

A simple brute force approach for the normal problems. At the best times during the lightning it could check about (2.5e6 programs / s) and for some problems I found solutions after having checked 900 million programs. I tried solving bonus problems by finding a partitioning of the example set so that I could find one solution separately for each partition and then a condition that would split the example set. There were some bonus configurations I didn't find a solution even when looking through the complete search space but no idea why.

The difficulty

• That's probably my only critic: problems advertised as hard were in general much easier than thought (also see the analysis: in average the solution size (~ 7.5) was only half the advertised (~ 16))
• Consequently, since I didn't expected to solve as many problems as I did, I didn't even try soon enough, so I finished the contest with 250 problems not even attempted because of the 15 req / minute constraint.
• Problems could have been run through a simplifier before calculating the metadata, this would have made it more likely that the problems would have fit their description

The analysis

The other files contain an analysis of the problems I solved by categories. Each line describes the properties and the solution of one problem.

A line look like this:

problem  5 [ 6|-02---] solution  5 [ 6|-02---] simplified  5 [ 6|-02---] <(lambda (x) (or x (plus x x)))>

and is read like this:

• The problem had an approximate search space of size 2^5.
• It was advertised with size 6 and with operators matching the flag section -02---.
• A flag section looks like this |bXYitf]
  • if it contains b, it was a bonus problem
  • if it contains i, it contained if0
  • if it contains t, it contained tfold
  • if it contains f, it contained fold
  • X is the number of unary operators
  • Y is the number of binary operators
• The same statistics is given for the solution as accepted and the solution as run through an optimizer (after the fact) to find a simpler solution
• The simplified solution itself

At the end of each section there's a size histogram which shows tuples (advertised size, number of problems with this size, average of log2 of search space traversed to find solution).

Lessons learned

• remember to register early and not only 10 hours after the contest has begun
• while it is possible to manage all alone it would be much more fun to participate in a team and much less stressful. One eye on the server to look out for bugs and strange things happening while trying to focus on improving the algorithm is hardly possible
• when implementing graph searches really test that nodes are traversed in the right order. If I had paid more attention to the problems being enumerated shortest solutions first, I could have avoided much trouble later on.
• I never know when Scala's collection are evaluated lazily and when not. Even trying to implement a Stream based solution (cf. Scala coursera course) seemed to break down after a certain depth of the problem. I still don't know which of Streams operations are always lazy and how much I can chain them without risking speed / StackOverflow problems.
• aborting Scala parallel collection loops (the most simple way of making things parallel, and also the most stupid in many cases) with non-local returns makes all threads run into a lock for some time: no good idea
• nevertheless Scala is a perfect language for fast prototyping if you know the tools

Tools

• Scala
• spray for communicating with the server
• parboiled for parsing

The code

Not the way I usually like it: completely raw, with all its last-minute improvement hackyness, commented code, trace message everywhere etc. can be found here: http://github.com/jrudolph/icfpc2013
