Need assistance with the minimax tree algorithm implementation.

[KonoDioDa22]

Hi,

So I am working on trying to implement the minimax tree algorithm given in the AI book. Here is the algorithm:

function MINIMAX-DECISION(state) returns an action
   return argmax_a _∈ _ACTIONS(s) MIN-VALUE(RESULT(state, a))

function MAX-VALUE(state) returns a utility value 
   if TERMINAL-TEST(state) then return UTILITY(state)
   v ←−∞
   for each a in ACTIONS(state)do
     v ← MAX(v, MIN-VALUE(RESULT(s, a)))
   return v

function MIN-VALUE(state) returns a utility value
  if TERMINAL-TEST(state) then return UTILITY(state)
  v ←∞
  for each a in ACTIONS(state)do
    v ← MIN(v, MAX-VALUE(RESULT(s, a)))
  return v

So if my problem is to return a max value from the input of a tree in a form of nested list, such as ((1,2,3),(4,5,6)), which after the minimax call, the output would be 4. What does the above algorithm mean by saying "ACTIONS, UTILITY, TERMINAL-TEST," and "RESULT(s,a)"? What are s and or a?
I am trying to understand this algorithm before I go ahead and attempt to implement it in C++.

Any clarification is appreciated.

Read the book again to find out.

I would not have been here if the book helped, or the Prof, or the TA or the students.

Sounds more like the Prof and the TA are the useless ones since they, according to you, do not know what they are teaching

seeings that it is a function call within a function call which is legal (btw), using the inside functions return ( value ) to pass it into the outside function.

MIN-VALUE(RESULT(s, a)))

s and a would therefore represent some type of variable value of some kind. what kind? One would need the documentation on same said function. seeings how it is dealing with values as you stated " such as ((1,2,3),(4,5,6)), w " I'd say it is an integer over a char.

So by the functions name it is the results of s and a that is being passed into, by the outside functions name, the minimum value. whatever operation that inner functions is preforming on s and a, but by its name one could logically deduce it maybe the lesser value between s and a

that is my best guess
