AI AND ROBOTICS (what is ai)

 Artificial Intelligence

Artificial Intelligence is composed of two words Artificial and Intelligence, where Artificial

defines "man-made," and intelligence defines "thinking power", hence AI means "a

man-made thinking power."

So, AI can be defined as, "It is a branch of computer science by which intelligent machines

can be created.

which can behave like a human, think like humans, and able to make decisions. Artificial

Intelligence (AI) is the branch of computer science that aims to create machines that can

think, learn, and act like humans.

“AI is the science and engineering of making intelligent machines, especially intelligent

computer programs.”

John McCarthy (Father of AI)

“Artificial Intelligence is the study of how to make computers do things which, at the

moment, people do better.”

Elaine Rich

“AI is the study of agents that receive percepts from the environment and perform

actions.”….. Russell and Norvig (in their book Artificial Intelligence: A Modern Approach)

“Artificial Intelligence leverages computers and machines to mimic the problem-solving and

decision-making capabilities of the human mind.” IBM

Day three of theory of computation

 1. Non-deterministic Finite Automata (NFA) 

Unlike a DFA, an NFA allows a machine to explore multiple paths simultaneously. 

• Definition: For a given state and input symbol, an NFA can transition to zero, one, or multiple states.
• Acceptance: A string is accepted if at least one possible path leads to a final state.
• Flexibility: NFAs are generally easier to construct than DFAs because you don't need to define transitions for every possible input or worry about "dead states". 

2. NFA with Epsilon Transitions (

$ϵ$

-NFA) 

An

$ϵ$

-NFA introduces the epsilon (

$ϵ$

) move, which allows the machine to change states without consuming any input symbol. 

• 

  $ϵ$
  -Closure: This is a critical Day Three concept. It is the set of all states reachable from a specific state using only
  

  $ϵ$
  transitions (including the state itself).
• Use Case:
  

  $ϵ$
  -NFAs are highly useful for combining smaller machines (e.g., when implementing the "union" or "star" operations in Regular Expressions). 

3. Equivalence of NFA and DFA (Subset Construction) 

The most important takeaway of Day Three is that NFAs and DFAs are equally powerful; they both recognize the same class of languages (Regular Languages). 

• Conversion: Any NFA can be converted to an equivalent DFA using the Subset Construction (or Powerset Construction) algorithm.
• State Explosion: While an NFA with
  

  $n$
  states is simpler, its equivalent DFA may have up to
  

  $2^n$
  states in the worst case.
