Dual variables are also known as shadow prices or Lagrange multipliers. They represent the change in the optimal value of the objective function when the right-hand side of a constraint is ...

Integer variables are variables that can only take whole numbers, such as 0, 1, 2, and so on. Binary variables are a special case of integer variables that can only take 0 or 1 values, often ...

Simplex Method: Used for multi-variable linear programming problems to find the optimal solution by pivoting through different feasible basic solutions. Graphical Method: Applied to two-variable ...

Abstract: The aim of this paper is to introduce a formulation of linear programming problems involving intuitionistic fuzzy variables. Here, we will focus on duality and a simplex-based algorithm for ...

We propose a novel locally affine-invariant constraint which can be exactly linearized and requires a lot fewer auxiliary variables than other linear programming-based methods do. The key idea behind ...
