Understand the convex bag first The convex package must first say the definition of convexity, the simple point is that the point of any two points in the plane neighborhood is in the neighborhood, then the neighborhood has convexity. With a simple scrutiny, it can be found that a point with a first order derivative discontinuity in the neighborhood must not be represented linearly by a set of dots. Further

Convex optimization Overview First, what is convex optimization Not strictly speaking, the convex optimization is in the scope of the standard optimization problem, the requirement of objective function and constraint function is a kind of optimization problem of convex function. second, the importance

Convex Hull (Only for Convex packets in two-dimensional planes) I. Definition Simply put, there is a set of N points in a two-dimensional plane S. Now you need to select a point set C, and the points in C form a convex polygon G, so that all points in the s set are either within g or on g, and the area of the convex po

Each convexity defect area has four signatures: the starting point (StartPoint), the end point (En

Just start to see this topic do not know what east, after looking at the problem of the big God to know is the stability convex hull, what is stable convex package? The so-called stability is to determine whether the original convex hull can be dotted, a larger convex hull, and the

ground. The Architect has alreadyestablished a Cartesian coordinate system and have precisely measured thecoordinates of all Castl E ' s vertices in feet. input Input contains Several test cases. The first line of all case contains Twointeger numbers N and L separated by a space. N (3 Next N Lines describe coordinates of Castle ' s vertices in a clockwise order. Each line contains-numbers XI and Yi separated by a space ( -10000 Process to end of file. OutputFor each case in the input,

Write a little something recently written ...Recently in the algorithm class, the class teacher talked about the Vinoto, I think it is very interesting to study a bit, and Java wrote a simple SE program used to show Vinoto and Delaunay triangles and convex package.First of all, the convex hull, convex hull in mathematics is very common, given some points, and the

Main topic:Given the n vertices of the polygon castle, build a fence around the castle, surround all the points, and the wall is at least as far from all points as L, seeking the smallest length of the wall.Ideas:The result equals the perimeter of the convex hull + the circumference of a complete circle.When walking around the castle, the Radian formed on the corner is added to a circle with a length of L.1 /*2 POJ 11133

[1] What is concave-convex ing The process of convex/concave ing involves extracting the texture and illuminating the surface with the internal information of the texture, so that the surface shows more details than it actually has. This process is done by using the normal value stored in the texture image rather than the surface normal value when the ry is illuminated. You can obtain the appearance details

The so-called convex hull is a concept in computational geometry (graphics). In the case of non-rigorous words, given a set of points on a two-dimensional plane, a convex hull is a convex multilateral type that joins the outermost point together, and it can contain all points in a point set. Wikipedia has four definitions for the

This is a half-plane of the naked problem, the first half-plane to write, just say I half-plane cross understanding it.The so-called half-plane intersection, is to find a large pile of two of yuan an inequality of the intersections, and each two yuan of the solution set of an inequality can be seen in a straight line above or below the standard equation of the contact line can be obtained. So these inequalities can be converted to some half-plane, which is half-plane intersection.The semi-planar

Question: Calculate the closest distance between two non-Intersecting polygon.Http://poj.org/problem? Id = 3608Here is a detailed explanation: http://cgm.cs.mcgill.ca /~ Orm/mind2p.htmlThis is to find the point in the lower left corner of the first convex bag, find the point in the lower right corner of the second convex, two parallel lines are stuck.And then start to rotate, divided into three situations:T

Test instructionsGives the midpoint, length, width and clockwise angle of n rectangles. Lets you wrap them up with the smallest convex polygon to calculate the percentage of the rectangular area that occupies the convex polygon.With the algorithm of convex hull given by large petition, each vertex of the rectangle is convex
