Optimality conditions

Optimality conditions are criteria used to determine when a solution to a problem is the best possible one, given certain constraints. For example, in maximizing profit or minimizing costs, these conditions help identify points where no further improvements can be made without violating the rules. They involve checking whether small changes to the solution would lead to better results; if none can, the current solution is considered optimal. These conditions ensure that the chosen solution truly meets the goals efficiently and effectively within the given limitations.
