A parameter is a fixed input value that defines an optimization problem but is not selected as a decision variable. It shapes the objective, constraints, or data used to evaluate candidate solutions. section 1.3.1
Ticket-pricing optimization
An event organizer chooses ticket price x to maximize profit. Fixed costs a and variable costs b are parameters: they describe the business conditions but are not optimized. The ticket price x is the decision variable, bounded by lower and upper limits, while expected demand Q depends on x. section 1.3.1
Keep the roles separate: parameters describe the problem being solved; decision variables are the values the optimization method searches for. Bounds are constraints on decision variables rather than parameters themselves. section 1.3.1
