What is the difference between the primal and dual?
The difference between primal and dual are that primal means an essential, or fundamental of an aspect where as dual means consisting of two parts or elements. Primal is one, dual is two.
Write the dual feasibility condition in dual simplex method?
In dual simplex, the initial basis is primal infeasible because some/all RHS elements are non positive. Same is dual feasible because the reduced costs (Cj's) are non negative. Throughout the algorithm, dual feasibility is maintained (by keeping the reduced costs > 0) while seeking primal feasibility. Once the solution is primal feasible, since it is also dual feasible, we have an optimal solution.
What is the significance of duality theory of linear programming?
fully understanding the shadow-price interpretation of the optimal simplex multipliers can prove very useful in understanding the implications of a particular linear-programming model.It is often possible to solve the related linear program with the shadow prices as the variables in place of, or in conjunctionwith, the original linear program, thereby taking advantage of some computational efficiencies.Understanding the dual problem leads to specialized algorithms for some important classes of linear programming problems. Examples include the transportation simplex method, the Hungarian algorithm for the assignment problem, and the network simplex method. Even column generation relies partly on duality.The dual can be helpful for sensitivity analysis.Changing the primal's right-hand side constraint vector or adding a new constraint to it can make the original primal optimal solution infeasible. However, this only changes the objective function or adds a new variable to the dual, respectively, so the original dual optimal solution is still feasible (and is usually not far from the new dual optimal solution).Sometimes finding an initial feasible solution to the dual is much easier than finding one for the primal. For example, if the primal is a minimization problem, the constraints are often of the form , , for . The dual constraints would then likely be of the form , , for . The origin is feasible for the latter problem but not for the former.The dual variables give the shadow prices for the primal constraints. Suppose you have a profit maximization problem with a resource constraint . Then the value of the corresponding dual variable in the optimal solution tells you that you get an increase of in the maximum profit for each unit increase in the amount of resource (absent degeneracy and for small increases in resource ).Sometimes the dual is just easier to solve. Aseem Dua mentions this: A problem with many constraints and few variables can be converted into one with few constraints and many variables.

Does Poland allow dual citizenship?
The rules of dual citizenship are quite easy to understand. Most countries neither deny or recognizes dual citizenship. However, if you are a dual citizen you must enter the country with the country's passport you own.

What is Dual aspect principle?
The dual aspect principle is a fundamental accounting concept that states that every financial transaction has two effects: a debit and a credit. This principle ensures that the accounting equation (Assets = Liabilities + Equity) remains balanced after each transaction, following the double-entry bookkeeping system. It helps maintain the accuracy and integrity of financial records by capturing the two aspects of an exchange or event.

Your 96 Chevy Taheo has single exhaust Will gas mileage increase by converting to dual exhaust?
depending on your driving, it could increase up to 4 or 5 mpg. But gas mileage will be determined by driving style.
What is a substance abuse dual diagnosis?
A substance abuse dual diagnosis refers to a situation where an individual is diagnosed with both a substance use disorder (such as drug addiction or alcoholism) and a mental health disorder (such as depression, anxiety, or bipolar disorder). This term highlights the complexity of treating individuals who struggle with both substance abuse and underlying mental health issues simultaneously.
