It might therefore not be considered wrong to use singular forms of abbreviations with plural numbers. No, $m:=\min\ {x,y\}$ is a random variable itself that records the lowest value of $x,y$ You do not compare the probabilities but the values of the random variables. 2、NL/min NL/min读作标准升每分钟，意思是20摄氏度，1大气压的标准状况下的流量是每分钟多少升。 体积流量 体积流量（Volume Flowrate）是单位时间里通过过流断面的流体体积，简称流量，以Q表示。 气体体积流量系指单位时间输送管道中流过的气体体积。 So yes, it's a function that, taken two elements, gives you the minimum of those. Nl/min是气流量的单位么?等于多少立方？ NL/min读作标准升每分钟，意思是20摄氏度，1大气压的标准状况下的流量是每分钟多少升。
What if the places are swapped, or some other combination Quadratic programming (convex optimization), linear programming, dynamic programming How does it differ from minimax? Find local max, min, concavity, and inflection points ask question asked 11 years ago modified 10 years, 11 months ago English pronunciation practice can be a challenging part of learning a new language, but our exercises and printables can help make practicing fun! Define $\arg\min_x f (x)$ as the set of values of $x$ for which the minimum of $f (x)$ is attained, so it is the set of values where the function attains the minimum.
Since linear functions are concave, so is the function $ (x_1,x_2,\ldots,x_n)\mapsto\min\ {x_1,x_2,\ldots,x_n\}$ and you may apply the jensen's inequality But of course, a more direct argument is possible, see galton's answer.
