利用Java程序分析福彩3D

發(fā)布時(shí)間：2023/12/14 java 34 豆豆

生活随笔收集整理的這篇文章主要介紹了利用Java程序分析福彩3D 小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

昨天寫了一篇利用Java程序統(tǒng)計(jì)彩票雙色球中一等獎(jiǎng)究竟有多難

今天突然來了興趣想利用java程序分析分析福彩的3D，雖然沒有買過這種彩票，但沖著作為一個(gè)程序猿對(duì)需求的敏感性，我決定試一哈

首先先分析了3D投注相關(guān)的規(guī)則?

---------------------------第二章? 投注第六條? 3D是指以三個(gè)號(hào)碼排列或組合為一注進(jìn)行單式投注，投注號(hào)碼由000-999組成，三個(gè)位置從左至右分別為“百位”、“十位”、“個(gè)位”，一組三個(gè)號(hào)碼的排列或組合稱為一注。每注金額人民幣2元。購(gòu)買者可對(duì)其選定的投注號(hào)碼進(jìn)行多倍投注，投注倍數(shù)范圍為2-99倍。單張彩票的投注金額最高不得超過20000元。第七條? 投注者可在福彩銷售機(jī)構(gòu)設(shè)置的銷售網(wǎng)點(diǎn)投注。投注號(hào)碼經(jīng)投注機(jī)打印出兌獎(jiǎng)憑證，交購(gòu)買者保存，此兌獎(jiǎng)憑證即為3D彩票。第八條??3D根據(jù)投注號(hào)碼的排列或組合分為“單選”、“組選”、“1D”、“2D”、“通選”、“和數(shù)”、“包選”、“猜大小”、“猜1D”、“猜2D”、“猜三同”、“拖拉機(jī)”、“猜奇偶”等投注方式，具體規(guī)定如下：（一）單選投注：是指對(duì)三個(gè)號(hào)碼以唯一的排列方式進(jìn)行投注。（二）組選投注：是指將三個(gè)號(hào)碼的所有排列方式作為一注投注號(hào)碼進(jìn)行投注。如果一注組選的三個(gè)號(hào)碼中有兩個(gè)號(hào)碼相同，則包括三種不同的排列方式，稱為“組選3”；如果一注組選的三個(gè)號(hào)碼各不相同，則包括六種不同的排列方式，稱為“組選6”。（三）1D投注：是指對(duì)百位、十位或個(gè)位中某一特定位置上的號(hào)碼進(jìn)行投注。（四）猜1D投注：是指對(duì)百位、十位或個(gè)位中任意一個(gè)位置上的號(hào)碼進(jìn)行投注。（五）2D投注：是指對(duì)百位和十位、十位和個(gè)位或百位和個(gè)位號(hào)碼，以唯一的排列方式進(jìn)行投注。（六）猜2D投注：是指對(duì)百位、十位或個(gè)位中任意兩個(gè)位置上的號(hào)碼進(jìn)行投注。（七）通選投注：是指對(duì)三個(gè)號(hào)碼以唯一的排列方式進(jìn)行投注。（八）和數(shù)投注：是指對(duì)三個(gè)號(hào)碼相加之和進(jìn)行投注。（九）包選投注：是指同時(shí)用單選和組選的方式對(duì)三個(gè)號(hào)碼進(jìn)行投注。如果三個(gè)號(hào)碼中有兩個(gè)號(hào)碼相同，則包括三種不同的排列方式，稱為“包選3”；如果三個(gè)號(hào)碼各不相同，則包括六種不同的排列方式，稱為“包選6”。（十）猜大小投注：是指對(duì)三個(gè)號(hào)碼相加之和的大、小性質(zhì)進(jìn)行投注。其中，三個(gè)號(hào)碼相加之和在19（含）至27（含）之間時(shí)為大，在0（含）至8（含）之間時(shí)為小。（十一）猜三同投注：是指對(duì)全部三個(gè)相同的號(hào)碼進(jìn)行投注。（十二）拖拉機(jī)投注：是指對(duì)全部以升序或降序連續(xù)排列的號(hào)碼進(jìn)行投注（890、098、901、109除外）。（十三）猜奇偶投注：是指對(duì)全部三個(gè)號(hào)碼的奇數(shù)、偶數(shù)性質(zhì)進(jìn)行投注。其中，1、3、5、7、9為奇，0、2、4、6、8為偶。---------------------------

確實(shí)簡(jiǎn)單，只有3個(gè)球，每個(gè)球可選0-9 ，只是投注方式比較多而已

目前福彩的獎(jiǎng)項(xiàng)是直選組三組六

直選是單選投注方式，只要投注號(hào)碼和中獎(jiǎng)號(hào)碼數(shù)字與位置都一致，即為中獎(jiǎng)

例子：中獎(jiǎng)號(hào)碼123 中出為 123

組三是組選投注方式，就是包括對(duì)子，不限位置，3個(gè)數(shù)中有兩個(gè)一樣的數(shù)字

例子：中獎(jiǎng)號(hào)碼122 中出為 122? ?212? ?221

組六是組選投注方式，就是3個(gè)數(shù)字都不相同，不限位置

例子：中獎(jiǎng)號(hào)碼123 中出為 123? ?132? ?213? ?231? ?312? ?321

好了開干，先從第一種最簡(jiǎn)單的方式單選投注開始吧

單選投注

首先是有一個(gè)得到一個(gè)0-9之間的隨機(jī)數(shù)字方法

然后執(zhí)行3次上面的方法，挨個(gè)得到三個(gè)號(hào)碼

跑一下試試?

組三投注

組三搖號(hào)與直選不一樣的地方在于三個(gè)數(shù)中有兩個(gè)要相同，同時(shí)在計(jì)算是否中獎(jiǎng)的方法上有所變動(dòng)

組六投注

組六搖號(hào)與直選一樣，不同的地方在于三個(gè)數(shù)中都不相同，同時(shí)在計(jì)算是否中獎(jiǎng)的方法上有所變動(dòng)

分析

對(duì)比上面的三種投注方式,隨機(jī)得出來的中獎(jiǎng)結(jié)果還是蠻詫異的

中獎(jiǎng)數(shù)量? ? 組三 > 組六 > 直選? 而且組三與組六中獎(jiǎng)數(shù)量幾乎是直選10倍左右

但細(xì)想了下我這塊的中獎(jiǎng)號(hào)碼是固定的，實(shí)際搖獎(jiǎng)號(hào)碼是隨機(jī)的產(chǎn)生導(dǎo)致的

所以綜合還要分析下組三與組六的出現(xiàn)的概率

組三出現(xiàn)的概率

private static int group3CountFunc1(int cpNum) {int luckyNum = 0;int countDownLatchNum = 1000;//線程數(shù)List<Integer> digits = digits(cpNum,countDownLatchNum);List<Integer> list = new CopyOnWriteArrayList<Integer>();//存放返回結(jié)果CountDownLatch countDownLatch = new CountDownLatch(countDownLatchNum);ExecutorService executorService = Executors.newFixedThreadPool(countDownLatchNum);for (int i = 0; i < countDownLatchNum; i++) {Runnable runnable = new Runnable(){@Overridepublic void run() {try {String name = Thread.currentThread().getName();String[] split = name.split("-");Integer threadId = Integer.parseInt(split[split.length-1]) - 1;Integer taskNum = digits.get(threadId);System.out.println("線程name:" + name + " \t執(zhí)行任務(wù)數(shù)量：" + taskNum);int luckyNumThread = group3CountFunc(taskNum);//System.out.println("線程name:" + name + " \t執(zhí)行完畢結(jié)果：" + cpOneNumRunnable);list.add(luckyNumThread);countDownLatch.countDown();} catch (Exception e) {e.printStackTrace();}}private int group3CountFunc(Integer taskNum) {int luckyNum = 0;String cpTempStr = "";for (int i=1; i<=taskNum; i++) {cpTempStr = getCp3dStr(getCp3dNums());if(isGroup3Num(cpTempStr)) {luckyNum++;}}return luckyNum;}/*** a-b-b* @param cpStr* @return*/private boolean isGroup3Num(String cpStr) {String[] split = cpStr.split("-");Map<String,Object> temp = new HashMap<String,Object>();for (int i=0 ; i<split.length; i++) {temp.put(split[i], i);}if(temp.size()==2) {return true;}return false;}};executorService.execute(runnable);}try {countDownLatch.await();} catch (InterruptedException e) {e.printStackTrace();}executorService.shutdown();for (Integer result : list) {luckyNum += result;}return luckyNum;}

取平均值計(jì)算后組3的出現(xiàn)的概率約為 0.27

組六出現(xiàn)的概率

private static int group6CountFunc1(int cpNum) {int luckyNum = 0;int countDownLatchNum = 1000;//線程數(shù)List<Integer> digits = digits(cpNum,countDownLatchNum);List<Integer> list = new CopyOnWriteArrayList<Integer>();//存放返回結(jié)果CountDownLatch countDownLatch = new CountDownLatch(countDownLatchNum);ExecutorService executorService = Executors.newFixedThreadPool(countDownLatchNum);for (int i = 0; i < countDownLatchNum; i++) {Runnable runnable = new Runnable(){@Overridepublic void run() {try {String name = Thread.currentThread().getName();String[] split = name.split("-");Integer threadId = Integer.parseInt(split[split.length-1]) - 1;Integer taskNum = digits.get(threadId);System.out.println("線程name:" + name + " \t執(zhí)行任務(wù)數(shù)量：" + taskNum);int luckyNumThread = group6CountFunc(taskNum);//System.out.println("線程name:" + name + " \t執(zhí)行完畢結(jié)果：" + cpOneNumRunnable);list.add(luckyNumThread);countDownLatch.countDown();} catch (Exception e) {e.printStackTrace();}}private int group6CountFunc(Integer taskNum) {int luckyNum = 0;String cpTempStr = "";for (int i=1; i<=taskNum; i++) {cpTempStr = getCp3dStr(getCp3dNums());if(isGroup6Num(cpTempStr)) {luckyNum++;}}return luckyNum;}/*** a-b-c* @param cpStr* @return*/private boolean isGroup6Num(String cpStr) {String[] split = cpStr.split("-");Map<String,Object> temp = new HashMap<String,Object>();for (int i=0 ; i<split.length; i++) {temp.put(split[i], i);}if(temp.size()==3) {return true;}return false;}};executorService.execute(runnable);}try {countDownLatch.await();} catch (InterruptedException e) {e.printStackTrace();}executorService.shutdown();for (Integer result : list) {luckyNum += result;}return luckyNum;}

取平均值計(jì)算后組6的出現(xiàn)的概率約為 0.72

在對(duì)比下面的獎(jiǎng)金圖組三單注獎(jiǎng)金是組六2倍但在出現(xiàn)概率上卻不是如此所以如果我要買的話還是會(huì)去買組六

再來看直選的概率?

大約是千分之一吧，概率雖然比組三和組六小了很多，但比起雙色球還是杠杠滴，所以還是值得一試的，畢竟生活不易~~

本文就先分析到這里了，?倉(cāng)促成文不當(dāng)之處，請(qǐng)各位讀者批評(píng)指正！
