# 4.5.1 Container Selection Method

(1) \[Select containers in the same sequence as the input container list]: The optimization goal is to load the containers (vehicles, boxes) in the specified order and number.

For example: a batch of cargoes needs to be filled with two 40GP first, and the remaining should filled with 20GPs.

On the container page, add 40GP first, then add 20GP; then change the number of 40GP to 2.

Finally, in the \[Loading Rules] interface, select \[Container Selection Method] as \[Select containers in the same sequence as the input container list], and the system will load the two 40GP first, and the remaining 20GP.

(2) \[Automatically select containers to minimize the quantity of containers used for loading]: The optimization goal is to use the least number of containers.

(3)\[Automatically select containers to minimize the cost of containers used for loading]: The optimization goal is to minimize the total cost of the container. To use this loading rule, you need to fill in the cost of the container on the container page.

(4) \[Select containers with the highest volume usage rate]: The optimization goal is to select the container with the highest volume usage rate.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.loadmaster.biz/4-ui-and-terminologies/4.5-loading-rules/4.5.1-container-selection-method.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
