relaxation
|
P' is a relaxation of P if: (1) the feasible region of P' contains the feasible region of P, and (2) the objective value in P', say F(x), is no worse than that of P, say f(x), for all x in the domain of P (for maximization, this means F(x) >= f(x) for all x in X).

relaxation
|
the process leading to the establishment of thermodynamic equilibrium in macroscopic thermodynamic systems. It should be taken into account that the equilibrium state can be determined by a large number of parameters, and the processes of achieving equilibria with respect to different parameters can go in different ways and at different rates. R is quantitatively characterised by the relaxation time.
