## How do you write a good evaluation function?

How do I write a good evaluation function for a board game?

- field index should be high.
- in the lower fields my fuel should be high, when coming to the end it should be low (maximum of ’10’ required to enter the goal)
- all ‘power-ups’ must be spent to enter the goal, so prioritize them.

## What is the evaluation function in the A ∗ technique?

What is the evaluation function in A* approach? Explanation: The most widely-known form of best-first search is called A* search. It evaluates nodes by combining g(n), the cost to reach the node, and h(n.), the cost to get from the node to the goal: f(n) = g(n) + h(n).

## Which function determines the quality of terminal state in game playing?

The state where the game ends is called terminal states. Utility(s, p): A utility function gives the final numeric value for a game that ends in terminal states s for player p. It is also called payoff function. For Chess, the outcomes are a win, loss, or draw and its payoff values are +1, 0, ½.

## What is the name of the function used in GBFS algorithm?

The Greedy BFS algorithm selects the path which appears to be the best, it can be known as the combination of depth-first search and breadth-first search. Greedy BFS makes use of Heuristic function and search and allows us to take advantages of both algorithms.

## What is the evaluation function of A * search *?

A* search. A* search corrects for the problem of “greed”. In evaluating a given node/state, it takes into account both the distance traveled so far and the estimate of distance to the goal.

## What are the basics of game playing algorithms?

Min-Max algorithm is mostly used for game playing in AI. Such as Chess, Checkers, tic-tac-toe, go, and various tow-players game. This Algorithm computes the minimax decision for the current state. In this algorithm two players play the game, one is called MAX and other is called MIN.
