What is the primary goal of Minimax algorithm?

• Minimize the time complexity of search.

• Maximize the depth of the search tree.

• Determine the optimal move in a two-player game.

• Minimize the number of nodes expanded during search.

In the context of constraint satisfaction problems, what does "arc consistency" refer to?

• The number of variables involved in the problem.

• The number of constraints in the problem.

• Ensuring that each variable is consistent with its neighboring variables according to the constraints.

• The complexity of the problem.
