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..
In this way, what is 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).
Similarly, what is feasible solution in Ada? A feasible solution is a solution in which the feasible set and search space as well as the solution space is the set of all the possible points of an optimization problem that satisfy the problem's constraints, in which include the qualities and inequalities as well as integer constraints.
Keeping this in consideration, what is the difference between optimal solution and feasible 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.
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.

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. Share a link to this answer. Copy link.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. It may stem from an error in specifying some of the constraints in your model, or from some wrong numbers in your data.What is a unique optimal solution?
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.What do you mean by basic feasible solution?
A constraint is active for a particular solution if it is satisfied at equality for that solution. A basic solution that satisfies all the constraints defining or in other words, one that lies within is called a basic feasible solution.What is optimality principle?

Objective Function: The objective function in a mathematical optimization problem is the real-valued function whose value is to be either minimized or maximized over the set of feasible alternatives. In problem P above, the set X is the feasible region.What is the meaning of feasible region?
In mathematical optimization, a feasible region, feasible set, search space, or solution space is the set of all possible points (sets of values of the choice variables) of an optimization problem that satisfy the problem's constraints, potentially including inequalities, equalities, and integer constraints.What is slack and surplus variable?
Slack and surplus variables in linear programming problem The term “slack” applies to less than or equal constraints, and the term “surplus” applies to greater than or equal constraints. If a constraint is binding, then the corresponding slack or surplus value will equal zero.What is slack variable in simplex method?
In an optimization problem, a slack variable is a variable that is added to an inequality constraint to transform it into an equality. As with the other variables in the augmented constraints, the slack variable cannot take on negative values, as the simplex algorithm requires them to be positive or zero.What is feasible region in LPP?
Answer. A feasible region is an area defined by a set of coordinates that satisfy a system of inequalities. The region satisfies all restrictions imposed by a linear programming scenario. The concept is an optimization technique.
