Write code to determine the accepted answer

R, 1 char

1

You can supply the id of an answer as a command line argument if you wish. :) Link to ideone.

Further elaboration

Since it is not practical for an answers to execute other answers (different languages, etc.) and evaluate them based on their result the only remaining way I can see for them to give a score is to use some code metric.

I have noticed that all other answers so far give a higher score to shorter programs. I believe this is the shortest code possible so it should rank high in the result of other answers.

How and what answer my code gives for other answers seams to be less relevant. The only important aspect is that others rank my answer high.

R, 1 char

0

Following up on @Andris's answer, there are now two codes that have a single character: Andris's and mine. Since we tie in the eyes of the other answers, neither of us have "won" outright, so my answer won't "win". :-)

Ruby, 368 char

require 'json'
require 'open-uri'
v='body';w="#{v}_markdown";s='comments'
x=if(d=JSON.parse(open("http://api.stackexchange.com/2.2/answers/#{ARGV[0]}?site=codegolf&filter=!%29r%28UkmOhmCPjXru-TDty").read)['items'][0]).include?(s) then d[s].map{|c|c[w].length*[1,c[w].index('`')||1,c[w].index('\n')||1].max}.reduce(:+) else -2 end
puts d['score']*150+5*(d[v].match(/<(..).*?\1.*?\1/m))[0].ord+x-$~.end(0)

Good luck!
