What if i got one "zero" in non-basic variable equations and all other vars. is negative values, shall i do another iteration or this is the optimum?
@henkie88 жыл бұрын
What if you have 2 equal non basic variable solutions as the largest values for a minimization problem. Which value should you choose or doesn't it matter because they are equal?
@sxmirzaei8 жыл бұрын
+henkie8 it does not matter which one you choose, because they both contribute to the objective function equally.

I want to know if i choose the most negative number in non basic variables to do a loop then i get all values positive in non basic variable then i will get optimal solution for this transportation problem?
@sxmirzaei8 жыл бұрын
+mohamed basem what is your objective function? Max or Min?
@riyoua7 жыл бұрын
what if it's a max problem ? are we going to look for the most mines values for none basic variables and then draw a loop then we will look for the minimum value for odd numbers ? or we will look for the maximum value for the odd number ?
@sxmirzaei7 жыл бұрын
If you recall, when solving a problem using a max or min problem, min test implementation is the same. similarly, if the objective function is maximization, then you need to find the most negative value for none-basic variables but the rest of the process is the same. it means that you draw a loop and then will look for the minimum value for odd numbers and so forth.

Please explain what should be done when m+n-1 does not equal to the no. allocated cells
@sxmirzaei7 жыл бұрын
In this case, you have a degenerate solution. Typically, this happens when you implement the min test and subtracting the min value of odd cells. if when you do the subtraction, two of the cells become zero, as oppose to one cell, then you have less than m+n-1cells that are basic. it means you have a basic variables that is actually zero. To resolve the issue and be able to solve the problem, you need to add a small amount (epsilon) to one of the two cells that have become zero. This way you can consider that cell as basic when you write the equations and also creating a loop for the next step, if needed.

@magdalenetam68368 жыл бұрын
what i mean is a Degeneracy problem
@sxmirzaei8 жыл бұрын
+Magdalene Tam in the degenracy condition, you can assume that the basic variable that has a value of zero can take a a very small value (epsilon). This way you can write your Ui+vj-Cij=0 equation for that cell and calculate the Ui and Vj associated to it. Also , you can include that cell as one of the corners when you create a loop. hope this helps.
