The correct answer is: A. Linear polynomial
A linear polynomial is a polynomial of degree 1, which means it has only one term. The general form of a linear polynomial is $ax+b$, where $a$ is the coefficient of the $x$ term and $b$ is the constant term.
In game playing algorithms, a linear polynomial is used to represent the utility function of a player. The utility function is a measure of how good a player feels about a particular state of the game. The coefficient $a$ represents the player’s preference for winning, and the constant term $b$ represents the player’s preference for avoiding losses.
For example, if a player’s utility function is $2x-1$, then the player would prefer to win by 2 points than to win by 1 point, and the player would prefer to avoid losing by 1 point than to avoid losing by 2 points.
The other options are incorrect because they are not polynomials. A weighted polynomial is a polynomial in which each term has a different weight. A polynomial is a mathematical expression that consists of one or more terms, each of which is a product of a number and a variable raised to a power.
