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.

If you’re able to control your typing to the microsecond, you’ll be able to influence the RNG pdo not much, because they also bring in things like “number of free sectors on the disk, system uptime, process id, Most players wouldn’t be able to evaluate “statistical norms” to save their life.
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. A document describing the process is available by emailing dealmaster at dealmaster. When four or five thousand deals have been created, there is significant data for an informed judgment re accuracy of the shapes compared to standard expected.
DM Pro uses a unique deal generation process. 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.
Hanoi5, on October, The data shows no bias toward excessive voids or singletons. Now, any bridge hand dealmastef that doesn’t do the BigBook method of generating hands now is being lazy and by lazy, I mean not reprogramming it.
Try this for abouthands and I think you will find that the match is quite close. No one has proven it cannot. BTW, I was also a math major. That requires a not so standard PC. Skin delamaster Language Language: Given that the number of bridge deals is a little less than 2 96one would edalmaster a 96 bit Mersenne Twister. While most of the hands are random, I’ve also noticed the relatively frequent occurance of non-random hands, or rather, series of non-random hands.
PrecisionL, on October, I don’t know how Big deal is implemented in Deal Master Pro, but it wouldn’t make dea,master sense to implement it without using the method Big deal uses to generate the random numbers. The data is accumulated. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such.
I don’t have hard numbers but I am convinced there is a correlation here. 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.
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. Remember – most peoples hand shuffling does not give random results. Finally, we believe DM Pro can create every possible bridge deal. 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.
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.
It includes a table with the frequencies for all possible hands. The above mentioned data prove its effectiveness. Community Forum Software by IP. 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.
I didn’t look at these hands but the test portion of the report proved that the results were as expected. Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i. After 90 days and 60 deals and prl, most players are not convinced that this program approaches statistical norms.

The program seems to function properly most of the time and then can go completely nuts all of a sudden. After a while people accepted the fact that they were now playing ‘really’ random deals yeah yeah, it’s not truely random, I knowwhile they weren’t in the past.
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? Yes the players still noticed a difference between computer hands and hand shuffled hands. I must admit that there were more wild distributions, but I don’t really care. Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be?
In that sample, DM Pro deals were slightly more accurate than BigDeal, but the difference is not significant.

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. Time to get over it If someone feels a specific program is being less than random, there must be ways of checking oro flaws and fixing them if found. Most shuffle only twice. 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.
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. The timing and location of the mouse clicks provide the randomness.
