For example, if there is another bidder Bob and he bids y {\displaystyle y} and y < a {\displaystyle y<a} , then Alice would like to bid y + ε {\displaystyle y+\varepsilon } (where ε {\displaystyle \varepsilon } is the smallest amount that can be added, e.g. one cent).
例如，如果有另一个竞拍者Bob，他的出价 y {\displaystyle y} 满足 y < a {\displaystyle y<a} ，那么Alice就会出价 y + ε {\displaystyle y+\varepsilon } （其中 ε {\displaystyle \varepsilon } 是她最低可以加的价格，例如1分钱）。
