What is diffierence between regular simplex method and dual simplex method?
Simplex method used for maximization, where dual simplex used for minimization.
What is the difference between the primal and dual?
The difference between primal and dual are that primal means an essential, or fundamental of an aspect where as dual means consisting of two parts or elements. Primal is one, dual is two.
Difference between simplex and dual simplex?
Simplex is usually used to describe a single strand of Fiber Optic cable. This is sometimes used when a signal only needs to go in one direction, like a simple video feed from a security camera. Duplex (sometimes called "zipcord") is two strands of Fiber Optic cable joined by a thin connection between the two jackets. This is much more commonly used than simplex as with two fibers you can get synchronous communication between devices. Duplex cables are often labeled with A and B to determine which is the transmit and which is the receive.
What is a self dual polyhedron?
For every polyhedron, there is a dual which is a polyhedron that has:a face where the first had a vertex,a vertex where the first had a face,the same number of edges.A self-dual polyhedron is a polyhedron whose dual is the same shape.All pyramids, for example, are self-dual.
How are platonic solids related?
One way in which Platonic solids are related is by duality. To construct the dual of a Platonic solid take the vertices of the dual to be the centres of the faces of the original. The lines joining adjacent centres of the original form the edges of the dual. In this way, the numbers of faces and vertices are swapped while the number of edges remain the same.A tetrahedron is its own dual.A hexahedron (cube) and octahedron from a dual pair.A dodecahedron (cube) and icosahedron from a dual pair.One way in which Platonic solids are related is by duality.
