Web13 feb. 2013 · These three requirements are referred to as the Hull-Dobell Theorem. While LCGs are capable of producing decent pseudorandom numbers, this is extremely sensitive to the choice of the parameters c , m, and a. Historically, poor choices had led to ineffective implementations of LCGs. WebThe theorem is often given in greater generality, though for our considerations, we will mainly apply it to the plane. We begin with a definition of a convex set. ... If the convex hull of these 4 points is a convex quadrilateral, WLOG let the points be ordered as $ a_1, a_2, a_3, a_4 $.
