Biconvex optimization refers to a class of optimization problems that involve a biconvex function. A function \\( f(x, y) \\) defined on a product space \\( X \\times Y \\) (where \\( X \\) and \\( Y \\) are convex sets) is considered biconvex if it is convex in \\( x \\) for each fixed \\( y \\), and convex in \\( y \\) for each fixed \\( x \\).
