Which term is described by “decision to choose a course of action for each play in accordance with some particular probability”?

"The _________ interchanges costs and constraints of the primal model, and converts the objective from maximization to minimization." Fill in the blank with the correct concept.

Which of the following is true regarding artificial variables?

What is the pivot number in the tableau above?

I. Check the optimality of the basic feasible solution as the simplex method does. If it is not, optimal, then move to the next step. If optimal, stop.

II. Iterate to the next basic feasible solution by determining the entering and leaving variable using the rate of improvement on the objective value.

III. Determine a basic feasible solution to initiate.

Which of the following is the correct order of the steps of solution of a transportation model?

What is the pivot number in the tableau above?

1. Identify the optimal solution by the coordinates of the zero-valued elements in the present matrix.
2. If the number of masked out rows and columns is equal to n, then the optimum can be obtained from the present matrix; move on to the next step. If not, skip to Step 6.
3. Identify the smallest value of each row for the cost matrix of the assignment problem. Subtract each row’s smallest value from all the costs in the respective row.
4. Identify the smallest value except for the ones in masked out rows and columns. This value is then subtracted from the values of unmasked rows and columns and, added to the intersections of masked out rows and columns. Return to Step 3.
5. Identify the smallest value of each column for this altered matrix. Subtract each column’s smallest value from all the costs in the respective column.
6. Mask the columns and rows out that have a zero value. The number of masked out rows and columns must be at a minimum.

Considering the items above, which of the followings does include the right phases of the Hungarian Method?
