翻译Agent 𝑐 𝑖 . In this paper, we regard each charging station 𝑐 𝑖 ∈ 𝐶 as an individual agent. Each agent will make timely recommendation decisions for a sequence of charging requests 𝑄 that keep coming throughout a day with multiple long-term optimization goals. Observation 𝑜 𝑖 𝑡 . Given a charging request 𝑞𝑡 , we define the observation 𝑜 𝑖 𝑡 of agent 𝑐 𝑖 as a combination of the index of 𝑐 𝑖 , the real-world time 𝑇𝑡 , the number of current avail able charging spots of 𝑐 𝑖 (supply), the number of charging requests around 𝑐 𝑖 in the near future (future demand), the charging power of 𝑐 𝑖 , the estimated time of arrival (ETA) from location 𝑙𝑡 to 𝑐 𝑖 , and the CP of 𝑐 𝑖 at the next ETA. We further define 𝑠𝑡 = {𝑜 1 𝑡 , 𝑜2 𝑡 , . . . , 𝑜𝑁 𝑡 } as the state of all agents at step 𝑡. Action 𝑎 𝑖 𝑡 . Given an observation 𝑜 𝑖 𝑡 , an intuitional design for the action of agent𝑐 𝑖 is a binary decision, i.e., recommending 𝑞𝑡 to itself for charging or not. However, because one 𝑞𝑡 can only choose one station for charging, multiple agents’ actions may be tied together and are difficult to coordinate. Inspired by the bidding mechanism, we design each agent 𝑐 𝑖 offers a scalar value to "bid" for 𝑞𝑡 as its action 𝑎 𝑖 𝑡 . By defining 𝑢𝑡 = {𝑎 1 𝑡 , 𝑎2 𝑡 , . . . , 𝑎𝑁 𝑡 } as the joint action, 𝑞𝑡 will be recommended to the agent with the highest "bid" value, i.e., 𝑟𝑐𝑡 = 𝑐 𝑖 , where 𝑖 = arg max(𝑢𝑡)

`!=` 是 Java 中的一种比较运算符，用于判断两个值是否不相等。而 `java.lang.Long` 是 Java 中的一个类，用于表示长整型数值。

如果要比较两个对象是否相等，应该使用 `equals()` 方法，而不是比较运算符。例如，要判断两个 `java.lang.Long` 类型的对象 `a` 和 `b` 是否相等，可以使用以下方式：

if (a.equals(b)) {
    // a 和 b 相等
} else {
    // a 和 b 不相等
}

如果要判断两个 `long` 类型的基本数据类型是否相等，可以使用比较运算符 `==` 或 `!=`。例如：

long a = 123;
long b = 456;
if (a != b) {
    // a 和 b 不相等
} else {
    // a 和 b 相等
}
