Goal Stack Planning
Explain goal stack planning with example.
Goal stack planning is one of the most basic and earliest planning techniques.
Here is what the stack contains:
2)operators – ADD, DELETE and PREREQUISITE list
3)A database that maintains current situation for each operator
Each sub-goal is solved separately and then the conjoined sub-goal is solved.
To do the S(C, A) operation all preconditions should be true. In the given problem CL(A) is not true.So, to make the state true , replace CL(A) by U(B, A) and write the preconditions of Unstack operator.
