新VP换算表.doc

新VP换算表介绍2012年1月，世界桥联规则与规章委员会新成立了一个下属委员会，叫计分委员会。该委员会于2012年8月世界智力运动会期间提交了一份报告，主要内容是新VP换算表的设计。新的换算方法意在保证每一个IMP的价值，即每多赢1IMP，都能在VP比分上得到体现。这样的换算方式已在一些比赛中采用，如2012年底在北京举行的智力精英运动会。据说将会于2013年开始在比赛中普遍使用。新的VP折算方式将会极大地影响桥牌比赛中的策略及战术，为了一个超墩进行申诉有可能成为普遍的现象。牌手们打牌的速度将会进一步放慢了。新的换算不再用表格方式进行，而是使用公式计算。详细方法如下： 1、基数B：比赛副数的平方根的15倍。2、黄金数tau，近似值为0.618，具体算法为5的平方根，减1后除以2。3、假设双方的IMP差值为M，算出tau的(3M/B)次乘方(设为x)，再算出tau的3次方(设为y)。4、(1-x)与(1-y)的比值的10倍(设为z)，就是对阵双方偏离平分的数值。即：胜方VP为10+z，负方VP为10-z，但最大不超过20:0。 新VP表的平局为10:10VP(满分改为20:0VP)，当IMP分差为B值的1/3时，胜方可得到15VP；当IMP分差为B值的2/3时，胜方可得到18.09VP；当IMP分差大于或等于B值时，即为20:0VP。赢多少IMP能得到VP的满分？对于16副的比赛是最好算的，因为16是个完全平方数，它的平方根乘以15为60，即分差达到60IMP即可拿到20VP。 对于8副牌的比赛，B值约为42.4；即分差达到43IMP时拿到20VP。 10副牌：47.4，分差达到48IMP时拿到20VP。12副牌：51.96，分差达到52IMP时拿到20VP。20副牌：67.08，分差达到68IMP时拿到20VP。新VP换算表副数81012基数b42.4264147.4341651.96152黄金数tau0.618034tau30.236068IMP差VPVPVP胜方负方胜方负方胜方负方010.0010.0010.0010.0010.0010.00110.449.5610.399.6110.369.64210.869.1410.779.2310.719.29311.278.7311.148.8611.058.95411.678.3311.508.5011.388.62512.057.9511.858.1511.708.30612.427.5812.197.8112.017.99712.777.2312.517.4912.317.69813.126.8812.837.1712.617.39913.456.5513.146.8612.907.101013.786.2213.446.5613.186.821114.095.9113.726.2813.456.551214.395.6114.015.9913.716.291314.685.3214.285.7213.976.031414.965.0414.545.4614.225.781515.234.7714.805.2014.465.541615.504.5015.054.9514.705.301715.754.2515.294.7114.935.071816.004.0015.524.4815.154.851916.233.7715.754.2515.374.632016.463.5415.974.0315.584.422116.683.3216.183.8215.794.212216.903.1016.393.6115.994.012317.112.8916.593.4116.183.822417.312.6916.793.2116.373.632517.502.5016.973.0316.553.452617.692.3117.162.8416.733.272717.882.1217.342.6616.913.092818.041.9617.512.4917.082.922918.211.7917.682.3217.242.763018.371.6317.842.1617.402.603118.531.4717.992.0117.562.443218.681.3218.151.8517.712.293318.831.1718.301.7017.862.143418.971.0318.441.5618.002.003519.110.8918.581.4218.141.863619.250.7518.711.2918.281.723719.370.6318.851.1518.411.593819.500.5018.971.0318.541.463919.620.3819.100.9018.661.344019.730.2719.220.7818.781.224119.850.1519.330.6718.901.104219.960.0419.440.5619.020.984320.000.0019.550.4519.130.874419.660.3419.240.764519.760.2419.340.664619.860.1419.440.564719.960.0419.540.464820.000.0019.640.364919.740.265019.830.175119.920.085220.000.00IMP差胜方负方胜方负方胜方负方VPVPVP副数81012新VP换算表副数141620基数b42.4264147.4341651.96152黄金数tau0.618034tau30.236068IMP差VPVPVP胜方负方胜方负方胜方负方010.0010.0010.0010.0010.0010.00110.339.6710.319.6910.289.72210.669.3410.629.3810.559.45310.979.0310.919.0910.829.18411.288.7211.208.8011.088.92511.588.4211.488.5211.348.66611.878.1311.768.2411.598.41712.167.8412.037.9711.838.17812.447.5612.297.7112.077.93912.717.2912.557.4512.317.691012.977.0312.807.2012.547.461113.236.7713.046.9612.767.241213.486.5213.286.7212.987.021313.726.2813.526.4813.206.801413.966.0413.746.2613.416.591514.195.8113.976.0313.616.391614.425.5814.185.8213.816.191714.645.3614.395.6114.015.991814.855.1514.605.4014.205.801915.064.9414.805.2014.395.612015.264.7415.005.0014.585.422115.464.5415.194.8114.765.242215.664.3415.384.6214.945.062315.854.1515.564.4415.114.892416.033.9715.744.2615.284.722516.213.7915.924.0815.454.542616.383.6216.093.9115.614.392716.553.4516.253.7515.774.232816.723.2816.424.5815.934.072916.883.1216.583.4216.083.923017.042.9616.733.2716.233.773117.192.8116.883.1216.373.633217.342.6617.032.9716.523.483317.492.5117.172.8316.663.343417.632.3717.312.6916.793.213517.772.2317.452.5516.933.073617.912.0917.592.4117.062.943718.041.9617.722.2817.192.813818.171.8317.842.1617.312.693918.291.7117.972.0317.442.564018.411.5918.091.9117.562.444118.531.4718.211.7917.672.334218.651.3518.331.6717.792.214318.761.2418.441.5617.902.104418.871.1318.551.4518.011.994518.981.0218.661.3418.121.884619.080.9218.761.2418.231.774719.180.8218.871.1318.331.674819.280.7218.971.0318.431.574919.380.6219.060.9418.531.475019.470.5319.160.8418.631.375119.570.4319.250.7518.721.285219.650.3519.340.6618.821.185319.740.2619.430.5718.911.095419.830.1719.520.4819.001.005519.910.0919.610.3919.080.925619.990.0119.690.3119.1
