unique optimal solution. Our method requires the solution of only one extra LPP such that the original problem has. alternative solutions if and only if the optimal value of the new LPP is positive. If the original solution is not unique, an. alternative solution is displayed.

Regarding this, what is an optimal solution?

An optimal solution is a feasible solution where the objective function reaches its maximum (or minimum) value – for example, the most profit or the least cost. A globally optimal solution is one where there are no other feasible solutions with better objective function values.

Also Know, what is the optimal solution in linear programming? Definition: An optimal solution to a linear program is the feasible solution with the largest objective function value (for a maximization problem).

Keeping this in consideration, what is the difference between feasible solution and optimal solution?

A feasible solution is a set of values for the decision variables that satisfies all of the constraints in an optimization problem. A local optimal solution is one where there is no other feasible solution "in the vicinity" with a better objective function value.

Do we always get an optimal solution in linear programming?

In linear programming we have a set of linear inequalities expressed in variables and a linear function we wish to minimise or maximise, expressed in the same variables. If the inequalities contradict each other, we might end up with an empty region, which implies that there is no 'optimal' solution.

### What are optimization techniques?

An optimization algorithm is a procedure which is executed iteratively by comparing various solutions till an optimum or a satisfactory solution is found. There are two distinct types of optimization algorithms widely used today. (a) Deterministic Algorithms. They use specific rules for moving one solution to other.

### What is unbounded solution?

An unbounded solution of a linear programming problem is a situation where objective function is infinite. A linear programming problem is said to have unbounded solution if its solution can be made infinitely large without violating any of its constraints in the problem.

### What do you mean by feasible solution?

A feasible solution is a set of values for the decision variables that satisfies all of the constraints in an optimization problem. The set of all feasible solutions defines the feasible region of the problem.

### What is the purpose of optimization?

610). The purpose of optimization is to achieve the “best” design relative to a set of prioritized criteria or constraints. These include maximizing factors such as productivity, strength, reliability, longevity, efficiency, and utilization. This decision-making process is known as optimization.

### What is the difference between feasible solution and basic feasible solution?

Feasible solution- A set of non negative individual allocation which satisfy all the given constraints is termed as feasible solution. Basic feasible solution(B.F.S) - For transportation problem if number of allocations are ten it is called as basic feasible solution.

### What is optimal basis?

The basis is optimal if the reduced costs are negative (for a maximization problem). The basis is {3,4}, so the non basic variables are x1 and x2. so if x1 enters the basis, the objective function will increase by 155/32 for every unit of x1: the basis {3,4} is not optimal.

### How do you find optimal value?

The optimal value is the lowest or highest value in the parabola. The axis of symmetry is always written like y= optimal value. This is an example of a question asking for the optimal value: Find the optimal value of this vertex form equation y=2(x+3)+9.

### What is a degenerate solution?

An Linear Programming is degenerate if in a basic feasible solution, one of the basic variables takes on a zero value. Degeneracy is caused by redundant constraint(s), e.g. see this example.

### What is initial feasible solution?

What is Initial Basic Feasible Solution IBFS? The solution of Minimization in operations research (also known as optimization) for our advantage in any scenario let it be transportation, resources, cost. This is known as Initial Basic Feasible Solution (IBFS).

### What do you mean by infeasible solution?

A linear program is infeasible if there exists no solution that satisfies all of the constraints -- in other words, if no feasible solution can be constructed. Since any real operation that you are modelling must remain within the constraints of reality, infeasibility most often indicates an error of some kind.

### What is basic feasible solution in LPP?

In the theory of linear programming, a basic feasible solution (BFS) is, intuitively, a solution with a minimal number of non-zero variables. Geometrically, each BFS corresponds to a corner of the polyhedron of feasible solutions. If there exists an optimal solution, then there exists an optimal BFS.

### What is pseudo optimal solution?

Δj ≥ 0 so according to optimality condition the solution is optimal but the solution is called pseudo optimal solution since it does not satisfy all the constraints but satisfies the optimality condition. The artificial variable has a positive value which indicates there is no feasible solution.

### What is LPP?

LPP stands for Linear Programming Problems. According to Wikipedia. It is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming.

### What is feasible solution in greedy method?

The Greedy method. General method: Given n inputs choose a sub- set that satisfies some constraints. – A subset that satisfies the constraints is called a feasible solution. – A feasible solution that maximises or min- imises a given (objective) function is said to be optimal.

### Can there be more than one optimal solution in linear programming?

The multiple optimal solutions will arise in a linear program with more than one set of basic solutions that can minimize or maximize the required objective function. The linear problem can be solved by using the software like MS Excel, but it only provides one optimal solution among many optimal solutions.

### What is a solution space?

The solution space is the set of all possible solutions for the combinatorial optimization problem. The solution space of the Vertex Separation Problem contains all the linear orderings of the vertices. Thus, the cardinality of the solution space of VSP is .

### What is LPP problem?

Linear Programming Problem and Its Mathematical Formulation. Linear Programming Problems (LPP) provide the method of finding such an optimized function along with/or the values which would optimize the required function accordingly.
