When the model function is continuous segment, its roughness does not depend on the behavior of the first segment, but depends on "h", the shift in the slope of two consecutive segments. If the distribution of design is uniform, f(x) is continuous segment function, and h is constant, then the maximum roughness is h2/192 obtained at the midpoint of the observations. Suppose that we have a sequence of designs {Pn(x)} then its corresponding distribution {Fn (x)} converges weakly to some distribution F(x). Let D(f) be a set of discontinuous points off(x), it is possible to take the limit of the roughness if D(f) has zero (dF)-measure. The behavior of maximum roughness of the discontinuous segment function has been studied by using grid points.展开更多

By using the two concepts of η-subdifferential and η-proximal mappings of a proper function, the authors try to demonstrate that the system of generalized mixed variational inequalities is equivalence with a fixed point problem. By applying the equivalence, a new and innovative η-proximal point algorithm for finding approximate solutions of the system of generalized mixed variational inequalities will be suggested and analyzed.
