Names for the number 0 in English the score was not placed upon a scoreboard, and there is scant evidence that the French ever used "l'oeuf" as the name for a zero score in the first place, that name being as anecdotal as the hypothesis that "love" is then derived from it. (Jacob Bernoulli, for example, in his "Letter to a Friend", used "à but" to describe the initial zero–zero score in court tennis, which in English is "love-all".) Some alternative hypotheses have similar problems. For example: The assertion that "love" comes from the Scots word "luff", meaning "nothing", falls at the first hurdle, because there is
Zero-sum game equivalent to linear programs, in general. If avoiding a zero-sum game is an action choice with some probability for players, avoiding is always an equilibrium strategy for at least one player at a zero-sum game. For any two players zero-sum game where a zero-zero draw is impossible or non-credible after the play is started, such as Poker, there is no Nash equilibrium strategy other than avoiding the play. Even if there is a credible zero-zero draw after a zero-sum game is started, it is not better than the avoiding strategy. In this sense, it’s interesting to find reward-as-you-go in optimal
