The class of decision problems solvable by a nonuniform family of Boolean circuits, with a linear number of wires, constant depth and unbounded fanin. Contained in LC0, and therefore strictly contained in AC0.
The class of decision problems solvable by a nonuniform family of Boolean circuits, with a linear number of gates, constant depth and unbounded fanin. Not to be confused with WLC0, which has a linear number of wires.
It is properly contained in AC0 [CR96].
