Minimum denied spectrum (MDS) assignment is a special case of minimum denied resource (MDR) optimisation applied to spectrum management, where frequencies are assigned to demands whilst satisfying the imposed constraints. MDR is pertinent to other applications including scheduling. MDS uses a look ahead cost function that takes account of the impact on demands to be subsequently assigned when making assignments. As a result the method attempts to avoid assignments which reduce the availability of spectrum to subsequent demands. Since the initial MDS paper (Bonsor (2001)) an effective method of backtracking has been incorporated. This allows more assignments to be made in the spectrum available whilst satisfying the assignment constraints or alternatively it offers the potential of reducing the spectrum needed, hence saving spectrum.
