One nit:<br />"A convex polygon is both x- and y-monotone, but the inverse is not true: A monotone polygon can be concave, as illustrated in Image 3."<br /><br />Image 3 is not a valid example for falsifying the converse implication, because it isn't x-monotone. You can instead spoil 5a which is both x and y-monotone but not convex.Anonymoushttps://www.blogger.com/profile/05167228071062893911noreply@blogger.comtag:blogger.com,1999:blog-4838136820032157985.post-22644752746340769802019-02-09T13:07:21.164-08:002019-02-09T13:07:21.164-08:00Image 3 is not x-monotone.

If you rotate it a little, it could be, but it's not as you present it.Joel Croteauhttps://www.blogger.com/profile/03471552894856748888noreply@blogger.com
