(Soft) constrain the number of adjacent channel interfering sources on lightpath (p,w) B is a large constant used to activate/deactivate the constraint Similarly we constrain the second-adjacent channel interfering sources Indirect (Parametric) IA-RWA algo Number of active adjacent channels (Affected PLIs: Intra-XT, XPM and FWM) (Soft) constrain the number of intra-XT interfering sources on lightpath (p,w) B is a large constant used to activate/deactivate the constraint Similarly we constrain the second-adjacent channel interfering sources Number of intra-channel XT sources Cαrry the surplus variables in the minimization objective
