# Intelligent Agents
|
||
|
|
*Any thing which can be viewed as perceiving its environment through sensors and acting upon that environment through its affectors*
|

|
## Reflex
|
||
|
|
|
||
|
|
## Goal Based
|
||
|
|
|
||
|
|
## Utility-based
|

|
|

|
# Environments
|
||
|
|
- (in)accessible
|
||
|
|
- (non)-deterministic
|
||
|
|
- (non)-episodic
|
||
|
|
- Static/dynamic
|
||
|
|
- Discrete/continuous
|
||
|
|
|
||
|
|
# Solving
|
||
|
|
1. Precise problem definition
|
||
|
|
- Start conditions and goal state
|
||
|
|
2. Problem analysis
|
||
|
|
- Appropriate representation
|
||
|
|
- Problem characteristics
|
||
|
|
- Knowledge intensive
|
||
|
|
- Decomposability
|
||
|
|
3. Choice of best technique
|
||
|
|

# Moves
|
||
|
|
- Ignorable
|
||
|
|
- Simple control structure
|
||
|
|
- Recoverable
|
||
|
|
- Backtrack using control stack
|
||
|
|
- Irrecoverable
|
||
|
|
- Much effort needed for each decision/move
|
||
|
|
|
||
|
|
|
||
|
|
- Control
|
||
|
|
- Cause movement
|
||
|
|
- Be systematic
|
||
|
|
- Be guided by heuristics
|
||
|
|
|
||
|
|
# Predictability
|
||
|
|
## 8 Puzzle
|
||
|
|
- Can plan ahead with certainty — only need a
|
||
|
|
control structure with backtracking
|
||
|
|
- recoverable, certain outcome
|
||
|
|
## Chess
|
||
|
|
- Future moves are not predictable with certainty.
|
||
|
|
- May need to consider several possibilities, and decide best option based on Incomplete information
|
||
|
|
- irrecoverable — once a piece is taken cannot in general recover from this state.
|
||
|
|
- deciding on an optimal move can be difficult
|
||
|
|
- try to predict opponent's move
