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.

It includes a table with the frequencies for all possible hands. Try this for abouthands and I think you will find that the match is quite close. 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. I don’t know how Big deal is implemented in Deal Master Pro, but it wouldn’t make much sense to implement it prp using the method Big deal uses to generate the random numbers. 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.
Thanks for the reply.
A document describing the process is available by emailing dealmaster at dealmaster. 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. 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.
Bridge Card Game Software Program | Bridge Simulator & Deal Generator
It would really help if someone knowledgeable in computer science took a deal,aster at the underlying code. Finally, we believe DM Pro can create every possible bridge deal. I must admit that there were more wild distributions, but I don’t really care.
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 dealmsater things like “number of free sectors on delamaster disk, system uptime, process id, No one has proven it cannot. That ended the controversy. There are a number of other dealing programs out there. 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 dealmastr holds an approximate club 5, for example the club 3, 4 or 6.
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. Oh, and the entropy-generators do handle “suspiciously repetitive same key typing” – i. All platforms have something sane for generating entropy and cryptographically-secure random numbers for seeds and such.
And then the complaints about the number of voids, singletons and 8-card suits started.
Dealmaster Pro for Bridge Players
PrecisionL, on October, Is it any wonder that hand shuffled hands are flatter with fewer singletons voids and long suits than there should be? 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. Skin and Language Language: The data shows no bias toward excessive voids or singletons. Hanoi5, on October, After 90 days and 60 deals and hands, most players are not convinced that this program approaches statistical norms.
One well liked program – BIg Deal – is now included in Dealmaster.
In that sample, DM Pro deals were slightly more accurate than BigDeal, but the difference is not significant. That requires a not so standard PC. I don’t have hard numbers but I am convinced there is a correlation here. Most shuffle only twice. You can do the same. Every time DM Pro deals are generated for club play, the user is invited to print dealmmaster statistical summary.
DM Pro uses a unique deal generation process. After a while people dealmasteer 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. In Big deal, the random generation is performed by involving input from the user. Then let all the superstitious people with selective memory about voids and such rpo out and complain and make fools of themselves before you actually switch.
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.
Yes the players still noticed a difference between computer hands and hand shuffled realmaster. The timing and location dealmster the mouse clicks provide the randomness. Time to get over it If dealmaeter feels a specific program is being less than random, there must be ways of checking for flaws and fixing them if found. Remember – most peoples hand shuffling does not give random results. Lro 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.
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.
I didn’t look at these hands but the test portion of the report proved that the results were as expected. Community Forum Software by IP. Have you ever watched your opponents shuffle in team games? I don’t know how this things work but I remember someone pr a deal generator in our federation in the 90’s and the seconds needle from the clock would start the randomness.
