Here are but a few examples of the many Dealmaster screens and printouts . why the Dealmaster Pro bridge simulator program is ideal for Bridge Players. Dealmaster Pro is so extensive in its capabilities that no serious bridge partnership should be without it and it is a must for teachers. You can restrict the dealing.

Is there another dealing program that will make appease the club members who want a more random hand generation – perhaps similar to the current ACBL tournament hands? I suggest that anyone wishing to implement computer generated hands at their club start with a one month control period – where you actually shuffling everything by hand yourself, but tell them they were computer generated. Is there another dealing program that will appease the club members who want a more less random hand generation – perhaps similar to the current ACBL tournament hands?

Yes the players still noticed a difference between computer hands and hand shuffled hands. Community Forum Software by IP. I don’t have hard numbers but I am convinced there is a correlation here. Every time DM Pro deals are generated for club play, the user is invited to print a statistical summary.

Time to get over it If someone feels a specific program is being less than random, there must be ways of checking for flaws and fixing them if found. Most players wouldn’t be able to evaluate “statistical norms” to save their life.

Finally, we believe DM Pro can create every possible bridge deal. Have you ever watched your opponents shuffle in team games? Dealmasher 90 days peo 60 deals and hands, most players are not convinced that this program approaches statistical norms. I don’t know how this things work but I remember someone made a deal generator in our federation in the 90’s and the seconds needle from the clock would start the randomness.

Dealmastter timing and location of the mouse clicks provide the randomness.

Dealmaster Pro

dealmater DM Pro uses a unique deal generation process. Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i.

Most shuffle only twice. Given that dealmasyer number of bridge deals is a little less than 2 96one would need a 96 bit Mersenne Twister. If you’re able to control your typing to the microsecond, you’ll be able to influence the RNG though not much, because they also bring in things like “number of free sectors on the disk, system uptime, process id, No one has proven it cannot.

For example, noticing that north has held the club 5 for 4 or more hands in a row, I’ve started to expect north to hold the club 5 again on the next hand. It includes a table with the frequencies for all possible hands. Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be? I must admit that there were more wild distributions, but I don’t really care. Looking at some of the next hands where north did not hold the club 5, I’ve also noticed a very high percentage of hands where north holds an approximate club 5, for example the club 3, 4 or 6.

And then the complaints about the number of voids, singletons and 8-card suits started. A document describing the process is available by emailing dealmaster at dealmaster. That ended the controversy. Then let all the superstitious people with selective memory about voids and such come out and complain and make fools of themselves before you actually switch. Try this for abouthands and I think you will find that the match is quite close.

That requires a not so standard PC. If the code, for example, uses the standard C library random number generator, these complaints are likely valid–it is a very poor random number generator intended for quick “randomish” values for testing–no one should use it for serious simulations such as bridge dealing where a good approach to randomness is desirable. If the code, on the other hand, uses a good random number generator such as the Mersenne Twister, I suspect we are seeing artifact of selective memories.


Generate a Hand Record

I realize that physical security is even now more of a danger than cryptanalysis, but we should be able to see the “set bits” and the BigBook “page” for every hand generated, on the hand records.

Delete From Topic The post will be removed from this topic completely. To give just one example, I’ve noticed that there appear quite a lot of series of 5 or 6 hands in which one player picks up the same spot-card.

One well liked program – BIg Deal – is now included in Dealmaster. There are a number of other dealing programs out there.

All platforms have dealmaaster sane for generating entropy and cryptographically-secure random numbers for seeds and such. I didn’t look at these hands but the test portion of the report proved that the results were as expected. Thanks for the reply.

Hanoi5, on October, It’s random number generator is mathematically more robust than the base one in Dealmaster, but no in a way that anyone would notice even if they played every day. You can do the same. The data is accumulated.

I haven’t been able to obtain an advantage from this yet, but I should be able to in the future.
