6. Consider the heuristics for this problem shown in the table above, h2 is admissible. 

 

true or false?

The image is a table that presents heuristic values for various states. It is structured with three columns: "State," "h1," and "h2."

- The "State" column lists different states labeled as S, A, B, C, D, E, and G.
- The "h1" column provides the heuristic value 1 for each state.
- The "h2" column provides the heuristic value 2 for each state.

Here are the values:

- State S: h1 = 3, h2 = 3
- State A: h1 = 3, h2 = 2
- State B: h1 = 5, h2 = 5
- State C: h1 = 2, h2 = 1
- State D: h1 = 3, h2 = 2
- State E: h1 = 4, h2 = 4
- State G: h1 = 1, h2 = 0

This table could be used to compare heuristic functions in algorithms such as A* to evaluate different paths or states in a search problem.

Expert Solution
Step 1

The condition for heuristic is that the H1 should be less that or equal to the path from the H1 to goal node .

H1<=*(H2)
