lottery algorithm generator

This article is mainly for you to introduce the PHP implementation of the large turntable lottery algorithm, with a certain reference value, interested in small partners can refer to The example of this article for everyone to share the PHP implementation of the Dial Lottery algorithm specific code for your reference,

This article will share with you the php winning probability algorithm, which can be used for scratch cards, big turntable, and other lottery algorithms. The usage is very simple. the code has a detailed description, which can be understood at a glance. For more information, see. First, complete the PHP process in the background. The main task of PHP is to configure the awards and the corresponding winning

Do site classes sometimes get an activity or something to allow users to participate, not only to attract users to register, but also improve the user activity of the site. At the same time to participate in the user will get a certain prize, there are 100% winners, there is a certain probability of winning, big such as the ipad, iphone5, small in the Q currency what the Then we in the program will inevitably design to the algorithm, that is, accordi

PHP lottery algorithm write lottery is nothing more than starting with probability, the probability of each level of prize is the percentage of the total weight of this weight $ Arr = array (Array ('prize' => 'first', 'weight' => 10 ),Array ('prize' => 'second', 'weight' => 10 ),Array ('prize' => 'third', 'weight' => 80)// Sort the weights in sequence, and ensu

What a better lottery algorithm for almighty Gods. Reply content: What a better lottery algorithm for almighty Gods. return False This is what I wrote earlier. Online with the popular is two algorithms, the probability is too high. Had to return to the textbook, and directly put all the winning ball and jammin

This time to bring you the use of PHP to implement the Turntable lottery algorithm case analysis, the use of PHP to realize the Dial lottery algorithm considerations are what, the following is the actual case, together to see. Process: 1. Assembling the prize array 2. Calculate probability 3. Return to the winning sit

Excerpt from the networkStatic voidMain (string[] args) { //The probability of each item is stored in the array . float[] area =New float[4]{ 0.5f, 0.5f, 0, 0 }; //One-time test//Console.WriteLine (Get (area)); //Batch Test int[] result =New int[4]{ 0, 0, 0, 0 }; for(inti =0; I 1770000; i++)//in order to be more convenient

5. Draw lots (code blanks)Planet X is sending a 5-man observer mission to the W-Star.whichA country can send up to 4 people.A maximum of 2 people can be dispatched in country B.C countries can send up to 2 people.....So how many different combinations of the country will eventually be sent to the W-Star's Observer mission?The following procedure resolves this problem.Array a[] is the largest number of places each country can send.The results of the program execution are:DefffCefffCdfffCdeffCcfff

The php winning probability algorithm is a typical probability algorithm used in lottery algorithms such as scratch cards and big turntable. * The key is that this algorithm has been applied in our previous projects, especially for projects with large data volumes, the efficiency is very good. $ ProCur) {$ randNum =

1. Algorithm AnalysisThe prizes are divided according to probabilities, each interval represents a prize, and then a random number is taken, and a counter-check falls on that interval, which is the prize drawn.2.

/** * Full probability calculation * * @param array $p Array (' A ' =>0.5, ' B ' =>0.2, ' C ' =>0.4) * @return String returns the key of the above array */ function Random ($ps) { Static $arr = Array (); $key = MD5 (serialize ($ps)); if (!isset ($arr [$key])) { $max = Array_sum ($ps); foreach ($ps as $k = = $v) { $v = $v/$max * 10000; for ($i =0; $i } } return $arr [$key][mt_rand (0,c

prize, and V indicates the probability of winning. Note that the V must be an integer, and you can set the V of the corresponding prize to 0, meaning that the odds of the prize being pumped are 0, the sum of V in the array (cardinality), and the larger the cardinality, the more accurate the probability. In this case, the sum of V is 100, then the winning probability of the tablet computer is 1%, if the sum of V is 10000, then the probability of winning is one out of 10,000.Every time a front-en

The example of this article for everyone to share the Java Lottery algorithm for your reference, the specific contents are as follows 1. Algorithm analysisaccording to the probability the prizes are divided into intervals, each interval represents a prize, and then the random number is extracted, and the retrieval falls on that interval, which is the prize. 2

value of K minus the probability space of the first number, in this case, minus 100, that is, the second number is filtered within the 1,900 range. In this way, there will always be a number to meet the requirements. is equivalent to go to a box to touch things, the first is not, the second is not, the third is not, then the last one must be. The algorithm is simple and very efficient, and the key is that it has been used in our previous projects, es
