How to create a good evaluation function for a game?
Sometimes, this is actually more of a concern, since a deep searcher with a medicore evaluation function can outplay shallow searches with a good evaluation function. It all depends on the domain. (gnubackgammon plays an expert game with a 1-ply search, for example)
Difference between heuristic function and evaluation function
2014年4月12日 · A heuristic function is a component of the evaluation function. An evaluation function estimates the cost of the cheapest solution through the given node, possibly taking into account more information about the node than just the state. A heuristic function also takes a node as input, however it's value only depends on the state at that node.
reinforcement learning - Game AI evaluation function and making ...
What I'm missing here is a way to direct the evaluation function to actually winning. For example, a perfect evaluation function for a won position in chess would always return +1 without any hint how to progress towards checkmate. In a chess variant without the fifty-move limit, it could play useless turns forever.
Minimax algorithm: Cost/evaluation function? - Stack Overflow
The simplest case of an evaluation function is +1 for a win, -1 for a loss and 0 for any non-finished position. Given your tree is deep enough, even this simple function will give you a good player. For any non-trivial games, with high branching factor, typically you need a better function, with some heuristics (e.g. for chess you could assign ...

2012年9月9日 · The evaluation function is responsible for providing a quick assessment of the "score" of a particular position - in other words, which side is winning and by how much. It is also called static evaluation function because it looks only at a specific board configuration.
What is an evaluation functional? - Mathematics Stack Exchange
2019年4月2日 · A concrete example is the evaluation function on the ring of polynomials over a field, ...
algorithm - Minimax Evaluation Function - Stack Overflow
2012年11月14日 · The problem I'm having is that the majority of examples I see on the internet show the evaluator function for tic-tac-toe. This is a lot simpler than the triple triad evaluator would be because the function would have to take into account the values on the card as well as the position it is being played in (e.g. taking an enemy card).
terminology - Is it standard to say that an evaluation function ...
Yes, "goodness" is a common description of the value generated by an evaluation function. For example, "Artificial Intelligence" p. 77; "Knowledge-Free and Learning-Based Methods in Intelligent Game Playing" p. 15; "Tenth Scandinavian Conference on Artificial Intelligence" p. 125; and "Algorithms and Networking for Computer Games" p.
algorithm - AI: How to find an evaluation function in this game ...
Now, this function might or might not work, but at least it will give you a starting point from which you can try to improve it or completely discard if it fails miserably. You can try to improve this evaluation function by tuning the coefficients, adding some non-linear terms to produce more complex relationships between the variables ...
How should I design a good evaluation function for Connect 4?
My problem now is the design of a good evaluation function for the state of the board (this is the value returned at maxDepth). The value is between -100 (worst choise,it corresponds to a losing situation) and 100 (best choise,it corresponds to a winning situation) where 0 is supposed to be "draw" situation .
