Selecting a variable to enter or leave the basis of a simplex tableau, facilitating the search for an improved optimal solution.

A Pivot element refers to an element of a matrix which is selected by an algorithm to proceed further calculations (e.g., with Gaussian elimination or simplex algorithm). 

Pivot Operation, it is the process of switching out appropriate rows and/or columns in a matrix to put a specific element on the diagonal.

The pivot operation is switching out appropriate rows and columns in a matrix to put a specific element on the diagonal.

on the video we watch pivot operation is a process which is we used in simplex method. Its function is to change or terminate the slack or constrains by the variable. And by iteration we can solve for optimal solution.

pivot operation is the interchange of suitable rows or columns of a matrix in order to place element on the diagonal.

It is switching out appropriate rows and columns in a matrix to put a specific element on the diagonal.

A pivot operation in the context of the simplex method is a fundamental step used to iteratively improve the current solution of a linear programming problem.

The pivot operation helps to move towards the optimal solution by iteratively improving the solution until an optimal solution is reached.
