An unbounded solution of a linearprogramming problem is a situation where objective function isinfinite. A linear programming problem is said to haveunbounded solution if its solution can be made infinitelylarge without violating any of its constraints in theproblem..
Thereof, what is infeasibility in linear programming?
A linear program is infeasible if thereexists no solution that satisfies all of the constraints -- inother words, if no feasible solution can be constructed. Since anyreal operation that you are modelling must remain within theconstraints of reality, infeasibility most often indicatesan error of some kind.
Also, what is optimal solution in linear programming? Definition: A feasible solution to a linearprogram is a solution that satisfies all constraints.Definition: An optimal solution to a linear programis the feasible solution with the largest objective functionvalue (for a maximization problem).
Similarly, it is asked, what is degeneracy in linear programming?
Degeneracy in a linear programming problemis said to occur when a basic feasible solution contains a smallernumber of non-zero variables than the number of independentconstraints when values of some basic variables are zero and theReplacement ratio is same.
What is unbounded solution in graphical method?
Unbounded Solution: Graphical Method inLPP It is a solution whose objective function isinfinite. If the feasible region is unbounded then one ormore decision variables will increase indefinitely withoutviolating feasibility, and the value of the objective function canbe made arbitrarily large.

Duality in Linear Programming. Definition:The Duality in Linear Programming states that everylinear programming problem has another linearprogramming problem related to it and thus can bederived from it. The original linear programming problem iscalled “Primal,” while the derived linearproblem is called “Dual.”What is degeneracy of transportation problem?
Degeneracy: Transportation Problem. If thebasic feasible solution of a transportation problem with morigins and n destinations has fewer than m + n – 1 positivexij (occupied cells), the problem is said to be adegenerate transportation problem. Degeneracy canoccur at two stages: At the initial solution.What is degeneracy how it is resolved in case of transportation?
In a standard transportation problem with msources of supply and n demand destinations, the test of optimalityof any feasible solution requires allocations in m + n – 1independent cells. If the number of allocations is short of therequired number, then the solution is said to bedegenerate.What is degeneracy in LPP How is it resolved?
An LP is degenerate if in a basic feasiblesolution, one of the basic variables takes on a zero value.Degeneracy is caused by redundant constraint(s) and couldcost simplex method extra iterations, as demonstrated in thefollowing example.What is the meaning of feasible region?
In mathematical optimization, a feasible region,feasible set, search space, or solution space is the set ofall possible points (sets of values of the choice variables) of anoptimization problem that satisfy the problem's constraints,potentially including inequalities, equalities, and integerconstraints.What is pseudo optimal solution?
Δj ≥ 0 so according to optimality condition thesolution is optimal but the solution is calledpseudo optimal solution since it does not satisfy all theconstraints but satisfies the optimality condition. The artificialvariable has a positive value which indicates there is no feasiblesolution. Page 5.What is unbalanced transportation problem?
