In linear programming, limits on the values of the variables are called "constraints." These constraints define the feasible region within which the solution to the optimization problem must lie. They can take the form of inequalities or equalities, restricting the values that the decision variables can assume. Constraints are essential in ensuring that the solution meets specific requirements or conditions of the problem.

What is a summary of linear programming?
It is a process by which a linear function of several variables, called the objective function, is maximised or minimised when it is subject to one or more linear constraints in the same variables.
What are the scope of linear programming?
Linear programming can be used to solve problems requiring the optimisation (maximum or minimum) of a linear objective function when the variables are subject to a linear constraints.
What is a structural variable in linear programming?
A structural variable in linear programming refers to a variable that directly influences the constraints and objectives of the model. These variables typically represent decision variables that determine the allocation of resources, such as quantities of products to produce or resources to allocate. They are essential for defining the feasible region of the optimization problem and play a crucial role in achieving the desired outcome in the linear programming formulation.
What is non linear programming problem?
It is a programming problem in which the objective function is to be optimised subject to a set of constraints. At least one of the constraints or the objective functions must be non-linear in at least one of the variables.
How do you from equations on linear programming?
To formulate equations for linear programming, first identify the decision variables that represent the quantities to be determined. Next, establish the objective function, which is a linear equation expressing the goal (e.g., maximizing profit or minimizing cost) in terms of these variables. Then, determine the constraints, which are linear inequalities representing the limitations or requirements of the problem. Finally, ensure that all variables are non-negative, as they typically represent quantities that cannot be negative.
What is linear Programming?
Linear programming is a technique for determining the optimum combination of resources to obtain a desired goal. It is based upon the assumption that there is a linear ,or straight line, relationship between variables and that the limits of the variations can be easily determined.
What is a summary of linear programming?
It is a process by which a linear function of several variables, called the objective function, is maximised or minimised when it is subject to one or more linear constraints in the same variables.
What type of linear programming can be found by graphical methods?
A linear programming question with two variables. Problems with three can be solved if there is a constraint that reduces them to effectively two variables. Linear programming with 3 variables, using 3-d graphs is possible but not recommended.
What are the scope of linear programming?
Linear programming can be used to solve problems requiring the optimisation (maximum or minimum) of a linear objective function when the variables are subject to a linear constraints.
What is the difference between linear and integer programming?
Integer programming is a method of mathematical programming that restricts some or all of the variables to integers. A subset of Integer programming is Linear programming. This is a form of mathematical programming which seeks to find the best outcome in such a way that the requirements are linear relationships.
To solve a linear programming problem with thousands of variables and constraints?
a mainframe computer is required
Characteristics of linear programming model?
1- single quantifiable objective ( Maximization of contribution) 2- No change in variables used in analysis 3- products are independent of each other 4- applicable in short term
What is non linear programming problem?
It is a programming problem in which the objective function is to be optimised subject to a set of constraints. At least one of the constraints or the objective functions must be non-linear in at least one of the variables.
What is the graph of a linear inequality in two variables called?
A bivariate linear inequality.
Can a linear programming problem have exactly two optimal solutions?
Yes, a linear programming problem can have exactly two optimal solutions. This will be the case as long as only two decision variables are used within the problem.
What is The first step in formulating a linear programming problem?
identifying any upper or lower bounds on the decision variables
