What is the gross margin per minute (rounded if necessary) of rivets manufactured using the spreadsheet on the previous slide? This means there are multiple optimal solutions to get the same objective function value. An alternate optimal solution is also called as an alternate optima, which is when a linear / integer programming problem has more than one optimal solution. Typically, an optimal solution is a solution to a problem which satisfies the set of constraints of the problem and the objective function which is to maximize or minimize. Alternative medicine is a term that describes medical treatments that are used instead of traditional (mainstream) therapies. It satisfies the following: 1. An optimization problem can be represented in the following way: 1. Solution: We can see from the diagram that the feasible set is bounded, so this problem will have an optimal solution for the maximum as well as for the minimum. Example: Here, the graphical analysis of a … Alternate optimal solutions occur mainly due to some portion of the polyhedron being parallel to the objective function. Answer (1 of 3): The certificate to prove optimality of an LP solution requires a solution to the dual LP that is feasible and complementary to your solution—that is, wherever your solution has a variable with a value away from its bound, the corresponding dual constraint is … This means there are multiple optimal solutions to get the same objective function value.
