Polyhedron convex optimization

How do you prove a polyhedron is convex?
Lemma 2 Any polyhedron P = {x ∈ n : Ax ≤ b} is convex.
Proof: If x, y ∈ P, then Ax ≤ b and Ay ≤ b.
Therefore, A(λx + (1 − λ)y) = λAx + (1 − λ)Ay ≤ λb + (1 − λ)b = b.
Thus x + (1 − λ)y ∈ P..
What is a convex polyhedron?
A convex polyhedron can be defined as a polyhedron for which a line connecting any two non-coplanar points on the surface always lies in the interior of the polyhedron.
A convex polyhedron is also known as platonic solids or convex polygons..
What is a polyhedron in optimization?
A polyhedron can represents the feasible set of an optimization program.
The program is infeasible when the polyhedron is empty.
Base.isempty — Function..
What is polyhedron in optimization?
Polyhedral optimization asks for the optimal value of a linear function, subject to constraints defined by linear inequalities.
The simplex method solves polyhedral optimization problems defined in normal forms..
What is the convexity of a polyhedron?
A convex polyhedron can be defined as a polyhedron for which a line connecting any two non-coplanar points on the surface always lies in the interior of the polyhedron.
A convex polyhedron is also known as platonic solids or convex polygons..
Why are polyhedra convex?
A polyhedron is considered to be convex when its surface i.e. face, edge, and vertex, does not intersect itself and a line segment joining any two points inside of a polyhedron is within the interior of the shape.
Some of the real-life examples of a convex polyhedron are cubes and tetrahedrons..

Jan 11, 2013A polyhedron can be defined as a finite intersection of halfspaces and hyperplanes. Halfspaces and hyperplanes are convex sets, the intersection Difference between convex set, closed convex set, polyhedron and why polyhedron was defined by linear equalities and inequalities?Proof that set is not a polyhedron. - Mathematics Stack ExchangeCheck whether a polyhedron is empty or notMore results from math.stackexchange.com

Polyhedral convex set optimization generalizes both scalar and multi-objective (or vector) linear programming. In contrast to scalar linear programming but likewise to multi-objective linear programming, unbounded problems can indeed have minimizers and provide a rich class of problem instances.

How can a convex polyhedron be obtained from a set of points?

A convex polyhedron may be obtained from an arbitrary set of points by computing the convex hull of the points

The surface defined by a set of inequalities may be visualized using the command RegionPlot3D [ ineqs , x, xmin, xmax, y, ymin, ymax, z, zmin, zmax ]

In computational geometry, the problem of computing the intersection of a polyhedron with a line has important applications in computer graphics, optimization, and even in some Monte Carlo methods.
It can be viewed as a three-dimensional version of the line clipping problem.
