Two transmit power constraints are also considered: (1) the classical total transmit power constraint (also known as the sum power constraint), and (2) An alternative constraint consists in limiting the peak-to-average power ratio; it is useful in practical scenarios where keeping the operation point in the linearity range of the amplifiers is especially important.
This constraint consists in forcing a component of this vector to be equal to 1.
The soft constraint consists in introducing a penalty function to discard solutions entering the constrained region [40, 64, 84].
The usual constraint, consisting in taking one level of age, period and cohort as a reference, i.e. equalising one parameter of each variable to 0, is not sufficient for identifying the model.
The model has been compared to a sequential model with the same constraints, which consists in solving the subproblems sequentially, and to a global model without reliability constraints.
The Min-Max hyperstructure equipartition with a connected constraint problem consists in partitioning a hyperstructure into K equal-sized connected parts that minimizes the maximum load in each part (the number of hyperedges assigned to each part).
Stravinsky once wrote that he could only be creative by working within strict constraints: "My freedom consists in my moving about within the narrow frame that I have assigned myself for each one of my undertakings".
Aerodynamic constraints consist of limits on power available in hover and forward flight.
Aerodynamic constraints consist of limits on power available in hover and forward flight, aerodynamic requirements (lift, drag and moment coefficients) for critical flow condition occurring on rotor blades.
The principle of constraint-based modeling consists in studying the set of reaction fluxes – namely flux distributions – that are achievable at steady state given the constraints imposed on the system.
