True or False? 1. If an LP has multiple optimal solutions, then all solutions have the same objective function value (such as total profit or cost). 2. As long as all prices (objective coefficients) change within their respective ranges, the optimal solution of a linear program does not change. 3. When a dual price changes within its range, the optimal solution does not change. 4. The solution of a linear program always consists of whole numbers (integers). That is why...
