Start by determining what data it works with. Then split out the functions and start figuring out the inputs and outputs from each function. Finally, make a process and data flow diagrams for the code. This process makes short work of understanding even the most cryptic code.
If you don't want to spend a day or two doing this process there are tools like sourcetrail that will do the work for you.

If the project is fairly significant in size with multiple .c and .h files with many functions, I will often turn doxygen (with graphviz) loose on it. Even though the code may not have any doxygen tags or doxygen-compatible comment blocks to generate function and API documentation, it can still give you an idea of "what calls what" in a graphical context.

My understanding of ranked voting is that a voter puts down his choices as an ordered set, and for the first round, the #1 votes are tallied; if no one has 50%+1, then the lowest vote-getter gets discarded, and everyone who had him as #1 simply have everyone else move up a place, and the process repeats.
As long as there aren't too many candidates - and indeed, there is hardly ever more than 6 candidates who get more than 2% of the vote - than a complete list pertaining to the permutations of the candidates could be released, and done so as they are counted, like a canonical election. I use the number 6 because 6! - 720 is still a digestible number. In fact, the law could be written so only that the first round eliminates everyone outside of the top-6.
For example, using this 6 number, the state's Secretary of State  could release the vote total of every permutation of the 6, and election-nerds like the gang at 538.com or the NY Times' (infamous) needle could crank the numbers as they see fit trying to put out the probabilities for the 6 at that instance.

There are different ways of implementing Ranked Voting.

Ranking all (or all-minus-one) options would be tedious if there were many.
I imagine that "ranking your top three" would simplify things considerably when there are a lot of options from which to choose.
Maybe something like "top three or the SQRT of the number of options" would suffice?

If we use bit groupings for the ranks of each candidate, that would look something like:
Bits per candidate: floor(log_2(candidateCount)) + 1
Bits per vote: candidateCount * bitsPerCandidate
Total space for election: voters * bitsPerVote
So given 300,000,000 voters with 12 candidates:
space = 300,000,000 * 12 * (floor(log_2(12)) + 1)
space = 14,400,000,000 bits or 1.8 GB
Given the same amount of voters with 24 candidates:
space = 300,000,000 * 24 * (floor(log_2(24)) + 1)
space = 36,000,000,000 bits or 4.5 GB
Space definitely isn't the issue. What about the algorithm?
1) Bin every vote by first-pick candidate.
2) If no bin is >50% of the votes, re-bin the lowest bin and repeat #2.
3) The >50% bin is your winner.
I honestly don't see why this would be an issue. Worst case scenario something like v+(c-2)*(v/2) run-time where v is the vote count and c is the number of candidates. v/2 is just a napkin-math average since the redistributed bins would start out small and grow as the candidate list got shorter.
Again, just a bunch of napkin math so I probably missed something but I never bought the "it's too hard to compute" excuse either  And I'm sure there are clever tricks to reduce the time required.
EDIT: For reference, if processing a vote takes:
1 microsecond: 30 minutes to determine a winner @ 300M votes, 12 candidates
1 millisecond: 20 days, 20 hours to determine a winner @ 300M votes, 12 candidates
And this is a single-threaded, un-optimized, brute-force approach.

And what exactly do you have against broccoli?
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
