Jan 29, 2023 · Let's consider these constraints: $2x_1 + x_2 \leq 4$ $-2x_1 + x_2 \leq 2$ $x_1 - x_2 \leq 1$ Also $x_1,x_2 \geq 0$ If we draw a graph, we'll see that the polytope formed only depends on the 1st and 3rd constraint, so the second constraint is redundant. However, the second constraint isn't a linear combination of the other two, since

In this video, you will learn what is meant by redundant constraints and how to identify that a linear programming problem has redundant constraints using th...

Jul 7, 2021 · A redundant constraint is one whose removal would not change the feasible region. Thus if the line for the constraint doesn't touch the feasible region, it's certainly redundant. If the feasible region has an edge along the line for this constraint (and for no other constraints), it …

Many researchers have proposed different approaches for identifying the redundant constraints in linear programming problems. This paper compares five of such methods and discusses the efficiency of each method by solving various size LP problems and netlib problems.

Among these 5 equality constraints, one is redundant, i.e. it is implied by the other constraints or, equivalently, it can be removed without modifying the feasible space. For example, by adding

Oct 1, 2019 · Linear programming problems consist of two parts are objective function and inequality constraints. A redundant constraint is a constraint that does not change the feasible region. There are many methods for detecting redundant constraint.

Many researchers have proposed di fferent approaches for identifying the redundant constraints in linear programming problems. This paper compares five of such methods and discusses the e ciency of each method by solving various size LP problems and ffi netlib problems.

In this paper, we develop deterministic methods for identifying all redundant linear constraints in semideflnite programming. We use a characterization of the normal cone at a boundary point and semidef-inite programming duality. Our methods extend certain redundancy techniques from linear programming to semideflnite programming.

In 2001, Ilya Ioslovich suggested an approach to identify the redundant constraints in LPP with help of one of the constraint. This constraint is said to be most restrictive constraint. The most restrictive constraint is identified after solving m sub LP problems.

Dec 23, 2010 · Many researchers have proposed different approaches for identifying the redundant constraints in linear programming problems. This paper compares five of such methods and discusses the...
