If people could only be happy with 99.+% Covermaster is usually close to optimal it's those final lines that can't be fit into the puzzle.A fast simplex that finds the perfect solution every time would be very valuable to the military industrial market. This is one reason people occasionally ask lottery software authors if they've found one. BobP

Quote: I have now to try and modify the code to set up a guarantee function to reduce the amount of combinations created. Thats actually the most important part. It will be really nice if you post it after finished or earlier if you experience any troubles...Good luck.

As apagogeas says, there is indeed no standard solution for this problem.I have not done much research on this matter, but if you cannot find a record breaking code there is at least a book that contains many record breaking wheeling systems. You'll probably find something in this book that suits your needs.http://www3.telus.net/lotbook/A year ago I found on some science website a free code that was able to generate some close to record breaking systems and also had set some real records. Unfort... [ More ]

Try a search for Cover by Authors: Kari J. Nurmela and Patric R. J. \ Osterg\aard. The source code used to be available for it. I have the zip not sure if the source code is in with the working copy as I haven't looked at if for years, send me an email that can accept a zipped reply attachment and I'll send you a copy. BobP

Dont forget that many of those extremelly good covering programs that accomplished those records are from the DOS , BASIC, and C time If those computers were able to make a cover in some reasonable time, I don't see why a current computers can't with some more success .the only it is necessary to adjust a little way that those old programs used to the new memory availability and processing speed However, I just had some ideas which seemed quite fine, and hope that soon will find some time to che...

Fenix,i would also be intersted in your idears if you would like to share!maybe we should all get to gether and work on this as a joint project

Fenix, brute force cannot work for bigger wheel sizes, even with 10 balls. I have my brute force program highly optimised in a manner that it does not check the same wheels, checks are ultra fast etc. You have no idea how many different acceptable wheels can be found. I'll give you an example because I have my program running 2 days now to compute an optimal wheel for Pick 4, 13 balls 2if4 (run on PII 450Mhz, even if we have more power the time problem remains, memory needed is less than 1MB).5...

great topic .when you will find this generator, please share it.the idea is to find a generator that produces the most optimized wheels. as said before, its not easy.

You already said it - a brute force method, and how well you might do depends only on the proccessor and the available memory....

Fenix, there is not a general solution to this problem. One approach that seems to provide better results, will not work so good on another case and this is why no program can be close to world records at higher wheel sizes. It seems to be an easy task but it is not. However, if you have some good ideas and want to share them, I think everyone would interested in that, including me.

I was thinking that such a code would be hard to get done. But after putting some ideas on a paper, it seems that it would be fairly easy to compose it. Therefore, really wonder why so far there is a shortage in coding accessibility regarding this matter

I have a brute force solution but this is efficient only for small sized wheels. Another one I work on is an improvement of brute force CoverMaster's solution including optimised sets definition. If you have done any research on this subject and concluded some useful results, contact me. The code is the least part. ThanksWhich is this post you refer to? I haven't noticed it

thanks for that wisdom!i must admit that i did think that this was the place to find help in this matter i was looking at a post yesterday about a system created by Systemx and he said he was going to post the code! i have sent him a mail but no reply as yet.how did you go with your search? did you manage to find the math requiered to construct the code?may be we should work together on this

I'm working on this subject for more than 1 year. Trust me, you'll not find any sort of code (I did that search for a long time too - I also asked for that here). Any such code is really precious especially if it can generate very good abbreviated wheels. What you can do, is to find some theoritical mathematical documents that deal with elements and theorems related to such wheels but this is rather difficult even to get a conclusion where to begin with.

ya i agree that its hard to find i have been looking for what seemes for ever!but there must be a mathamatical equation that can be converted to vba code for this and the lotto has been around for a long time now! i would have expected that there would have been lots of code floting around.i am in the process of making a new system of my own as i have several systems all of which have some good parts and some bad, i am trying to put all the good bits in to one system.

Really hard to find such a thing for free. Generating a good abbreviated wheel is a really hard task, especially if you aim to be close to world records. One of the simplest - ans still good - approaches is the one implemented in CoverMaster. I'm really curious about ININUGA optimisation (shrinking) method. I haven't figured it out yet.

Wheeling System generator Code?

Does any one know where I can get some source code for an abbreviated Wheeling system generator in vba or vb code
