Matching % logic between two user profiles -


i algorithm or formula or equation find matching % between 2 users based on attended questions. please find below example 1 case.

total: 200 q user a: 100 q user b: 120 q common : 90 q common correct: 60 q matching % of & b = ?

mind if both users have 1 common question , matched still should not 100% match similar okcupid site difference don't have importance of question , not expected answer option in question

can please me prepare formula find matching %?

thanks

if answers not important, seems that

matching = common / usera * common / userb

matching changes 0 (no common questions) 1 (user a , user b answered same set of questions).

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
