WebSep 17, 2016 · If M is chosen sufficiently large and m is sufficiently small (i.e., negative and large in absolute terms), this big-M reformulation is equivalent to the original constraint. If y is 1 (true), the only feasible x is 0, and our goal is accomplished. The complications arise when y is 0 and x should be unconstrained. For x to be unconstrained in this case, M has …

Consider the general case when the input to the algorithm is a finite unordered set of points on a Cartesian plane. An important special case, in which the points are given in the order of traversal of a simple polygon's boundary, is described later in a separate subsection. If not all points are on the same line, then their convex hull is a convex polygon whose vertices are some of the points in the input set. Its most common representation is the list of its vertices orde…
