🚩sum是“数字相加的结果”,柯林斯解释为In mathematics, the sum of two numbers is the number that is obtained when they are added together.。它还可指“全部,所有”,柯林斯解释为The sum of something is all of it.。这两个意义都习惯用单数名词。 如: The sum of all the angles of ...
For these games, the sum of the two players' payoffs is always zero; hence, a single number (the amount won by the first player, and therefore lost by the second) determines the payoff. In the finite case, the normal form for such a game is a matrix (as inFig. 2), with each ...
Consider a two-dimensional input array, A: sum(A,1) operates on successive elements in the columns of A and returns a row vector of the sums of each column. sum(A,2) operates on successive elements in the rows of A and returns a column vector of the sums of each row. sum returns...

Here’s a formula that uses two cell ranges:=SUM(A2:A4,C2:C3)sums the numbers in ranges A2:A4 and C2:C3. You’d press Enter to get the total of 39787. To create the formula: Type=SUMin a cell, followed by an opening parenthesis(. ...
For example, If you're trying to sum two text from two cells using a formula like =A3 + B3, and one of the cells (let's say cell B3) contains text instead of a number, Excel won't be able to perform the addition operation because it can't add a text and text together. As a...
For example, to average numbers in the row to the left of the cell, clickAVERAGEand type LEFT: =AVERAGE(LEFT) To multiply two numbers, clickPRODUCTand type the location of the table cells: =PRODUCT(ABOVE)
In this work, two-player zero-sum stochastic games, under imperfect information, are investigated in the discrete- time/discrete-state case. We focus on the case where only one player, Blue, has incomplete or partial information and the other player, Red, has complete state information. In st...
描述 给一个整数数组,找到两个数使得他们的和等于一个给定的数 target。 你需要实现的函数twoSum需要返回这两个数的下标, 并且第一个下标小于第二个下标。注意这里下标的范围是 0 到 n-1。 样例 Example1: 给出numbers = [2, 7, 11, 15], target = 9, 返回 [0, 1]. ...
This chapter is devoted to the study of Nash equilibria, and correlated equilibria in both finite and infinite games. We restrict our discussions to only those properties that are somewhat special to the case of two-person games. Many of these properties fail to extend even to three-person gam...
