2014年的12月29日,写了个VBS脚本,计算还需要连胜多少把才能让自己的胜率提升1%:
这个脚本的地址在:
结果后来连着输了几把,胜率掉了1%(汗)。正好昨天看了下QBasic,就用QBasic写段代码计算一下吧
我的编码环境为:编译器为Win32下的FreeBasic(版本1.00.0),IDE为FBIde(版本0.4.6r4)
这段代码计算了还需要连胜多少把才能把自己的胜率提升1%,也计算了还需要连败多少把就会让胜率降低1%
计算规则:
1)以当前玩了426局,获胜86局为例,当前的胜率是0.201878,截去小数后是20%。
2)在这个基础上,连胜4局后,玩了430局,获胜90局,胜率为0.209302,截去小数后还是20%;但在连胜5局后,玩了431局,获胜91局,胜率到达0.211137,截去小数后胜率到达21%!这个时候,就认为是连胜5局后,就可以让胜率增加1个百分点。
3)同理,计算负场时,连负4局后,玩了430局,获胜86局,胜率为0.2,即20%;连负5局后,玩了431局,获胜86局,胜率为0.199536,截去小数后,是19%,视为胜率下降一个百分点。
需要注意的几点是:
1)胜率100%的时候,再连胜多少局胜率都是100%
2)胜率99%的时候,再连胜多少局胜率都是99%
3)胜率0%的时候,再连负多少局胜率都是0%
程序代码如下:
