What is simplex method of linear programming with an example?
simplex method, standard technique in linear programming for solving an optimization problem, typically one involving a function and several constraints expressed as inequalities. The inequalities define a polygonal region, and the solution is typically at one of the vertices.
What is simplex algorithm?
The simplex algorithm, developed by George Dantzig in 1947, is the first practical procedure used to solve the LP problem. Given a set of n-variable linear constraints, the simplex algorithm first finds a basic feasible solution that satisfies all the constraints.
How can we solve linear programming problems using simplex method?

We need to start from an initialMoreTo be able to solve an optimization problem with a simplex method. We need to start from an initial feasible. Solution this initial feasible solution is usually found by introducing slack variables.
What is linear programming algorithm?
More formally, linear programming is a technique for the optimization of a linear objective function, subject to linear equality and linear inequality constraints. … A linear programming algorithm finds a point in the polytope where this function has the smallest (or largest) value if such a point exists.
How do you find the simplex method?
THE SIMPLEX METHOD

What is linear in linear programming?
Linearity – The relationship between two or more variables in the function must be linear. It means that the degree of the variable is one. Finiteness – There should be finite and infinite input and output numbers. In case, if the function has infinite factors, the optimal solution is not feasible.
