Polynomial Identity Testing (PIT) is a problem in computer science and computational algebra that involves determining whether a given polynomial is identically zero. In other words, given a polynomial \\( P(x_1, x_2, \\ldots, x_n) \\) expressed in some algebraic form, the task is to decide if \\( P(x_1, x_2, \\ldots, x_n) = 0 \\) for all possible values of its variables.
