### Project Euler Statistics

At least one user of python complained about the slowness of python. It is quite possible you start with one language and over time you try out a few more, but when someone gets to, say, having solved 300 problems, and has chosen languagex as hisher preferred language then they are doing that based on a lot of experience. It is easy enough to imagine people working doing the reverse, setting their language as what they get paid for, but programming in another.

There seems to be a small bug on the statistics page the of users for a language on that page doesnt always match the number of users on the languages page. Problems are of varying difficulty but each is solvable in less than a minute of cpu time using an efficient algorithm on a modestly powered computer. ).

Though this problem is much simpler than the typical problem, it serves to illustrate the potential difference that an efficient algorithm makes. The 13 users counted too many for mathematica (849 vs 836) may not change that languages user average, but rpl and cobol are currently reported 4 lower because of this mismatch. For this problem, we can reduce 1000 operations to a few by using the displaystyle beginalignedmathrm sum text3 or 5(n)&mathrm sum 3(n)mathrm sum 5(n)-mathrm sum 15(n)mathrm sum k(n)&sum i1leftlfloor frac n-1krightrfloor kisum i1pki&kfrac (p1)p2endaligned ) and the efficient algorithm is o(1) (assuming constant time arithmetic operations).

I appreciate that some languages are better suited to some problems than others, and some members might diligently go back and change their preferred language for problemy, but the idea is to capture a snapshot of the best all-round language in the view of our members. This method is simple to implement, as shown by the following set total to 0for num from 1 through 999 do if num mod 3 0 or if num mod 5 0 then add num to totaloutput total for harder problems, it becomes increasingly important to find an efficient algorithm. I am glad to have the apljk choice.

By reading in private forums for problems i got the impression that the people who are listed in the table of veterans or eulerians most of the time really used the languages they set to solve the problems. . This is not even a joke im currently implementing the miller-rabin algorithm in c and planning to call it from haskell using its foreign function interface to finally solve those nasty problems involving prime tests.

The point is that it should reflect the language which that member feels is best suited to solving project euler problems in general. I personally use haskell for most problems but occasionally switch to d or c. Because i solve problems in either apl or j (k is too ragged for me. Conversely, the most successful languagesprogrammers identify as using obscure languages, frink, pari, magma, etc. Special awards exist for solving special combinations of problems, for instance there is an award for solving fifty prime numbered problems.

Project Euler Statistics If you have forgotten your username and/or password and you have generated an emergency . If there already is per-submission accounting of language statistics, would it not be quite easy to add a language combo box for selection at submission time? Every hour the statistics are updated and calculations are based on the current language preference. Jan 11, If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3. ). By reading in private forums for problems i got the impression that the people who are listed in the table of veterans or eulerians most of the time really used the languages they set to solve the problems. I did some analysis of . Even though java has several user with over 300 solved, it also has about 400 users with 1 solved, and god knows how many more with less than 10 solved.

The average user rating is apparently affected by this. Special awards exist for solving special combinations of problems, for instance there is an award for solving fifty prime numbered problems. There seems to be a small bug on the statistics page the of users for a language on that page doesnt always match the number of users on the languages page. Project euler (pe) provides some statistics, but i wanted to see the effectiveness of the languages in solving problems. A forum specific to each question may be viewed after the user has correctly answered the given question.

This is not even a joke im currently implementing the miller-rabin algorithm in c and planning to call it from haskell using its foreign function interface to finally solve those nasty problems involving prime tests. Can someone in the know confirm that it is really true that changing the preferred language before solution submission will update statistics in favor of that language, no matter what the preferred language is later set to? I assumed that the statistics are compiled from whatever users current language preferences are, which would mean that all submissions of any one user go toward one language only. This method is simple to implement, as shown by the following set total to 0for num from 1 through 999 do if num mod 3 0 or if num mod 5 0 then add num to totaloutput total for harder problems, it becomes increasingly important to find an efficient algorithm. The sum of these multiples is 23. The project attracts adults and students interested in.

If we allowed a per problem choice then it would not reflect necessarily the best language for that problem as much as the language heshe knew at the time they solved the problem. Thanks for the clarification, euler! Some of us would probably prefer to know how many problems where solved in what language, but your overall best interpretation makes sense, too, of course. There are solvers who use several languages. Conversely, the most successful languagesprogrammers identify as using obscure languages, frink, pari, magma, etc. I personally use haskell for most problems but occasionally switch to d or c. It is quite possible you start with one language and over time you try out a few more, but when someone gets to, say, having solved 300 problems, and has chosen languagex as hisher preferred language then they are doing that based on a lot of experience. But, for the sake of statistics, i will start doing so from now. The point is that it should reflect the language which that member feels is best suited to solving project euler problems in general.
