Planning

Planning is finding a sequence of actions to solve a goal.

Explicit State-Space Representation

• The states are specifying the following:

• the robot’s location,

• whether the robot has coffee,

• whether Sam wants coffee,

• whether mail is waiting,

• whether the robot is carrying the mail.

⟨lab,

¬rhc,swc,

¬mw,rhm⟩

狀态空間

comp3411-week7輔導

先羅列狀态空間,然後基于狀态去寫action,最後寫plan求解。

STRIPS

如果寫出所有的狀态空間,全部用常量的原子表示,那工作量太大了。

是以使用STRIPS表示的方法,隻寫兩部分:

  1. 某動作的前置條件
  2. 某動作的結果

Feature-Based Representation

strips以及feature-based representation 都屬于對于整個行為狀态的表示方法。

Forward Planning

​這個是重點!​

​ assignment用的就是這個内容!

Regression Planning (Backward Search)
