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? The above mentioned data prove its effectiveness. 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.

In Big deal, the random generation is performed by involving input from the user. That requires a not so standard PC. It includes a table with the frequencies for all possible hands. I didn’t look at these hands but the test portion of the report proved that the results were as expected. That ended the controversy. Hanoi5, on October, Yes the players still noticed a difference between deqlmaster hands and hand shuffled hands.

Thanks for the reply. A document describing the process is available by emailing dalmaster at dealmaster. I don’t know how Big deal dealmsster implemented in Deal Master Pro, but it wouldn’t make much sense to implement it without using the method Big deal uses to generate the random numbers. 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?


The data is accumulated. Now, any bridge hand cealmaster that doesn’t do the BigBook method of generating hands now is being lazy and by lazy, I mean not reprogramming it. BTW, I was also a math major. I’m sure if I was playing FreeDoom in another window, it would have gone faster: True, but my partner is a math major and I am a statistics minor and both of us are suspicious of the non-randomness of the hands so far.

Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be? You can do the same. It did about 22 before it blocked not enough entropyand after that it took about 10, 15 seconds of playing around to get another set.

The timing and location of the mouse clicks provide the randomness. 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. Given that the number of bridge deals is a little less than 2 96one would need a 96 bit Mersenne Twister.

There are a number of other dealing programs out there.

The program seems to function properly most of the time and then can go completely nuts all of a sudden. 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, Have you ever watched your opponents shuffle in team games?

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.

Try this for abouthands and I think you dwalmaster find that the match is quite close.

In that sample, DM Pro deals were slightly more accurate than BigDeal, but dealmaater difference is not significant. After 90 days and 60 deals and hands, most players are not convinced that this program approaches statistical norms.

Most players wouldn’t be able to evaluate “statistical norms” to save their life. PrecisionL, on October, One well liked program – BIg Deal – is now included in Dealmaster.

Dealmzster platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such. Trinidad, on October, Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i. Time to get over dealmasteer If someone feels a specific program is being less than random, there must be ways of checking for flaws and fixing them if found. DM Pro uses a unique deal generation process. And then the complaints about the number of voids, singletons and 8-card suits started.

Remember – most peoples hand shuffling does not give random results. The data shows no bias toward excessive voids or singletons.
