Abstract
The inventive 2-step-optimization procedure that addresses the generalized routing and wavelength assignment problem with variable number of combined 1+1 dedicated and shared connections for the first time. The proposed procedure results a solution in time that is polynomial of the input size. Thus, the time complexity of the 2-step-optimization procedure is significantly less than that of existing methods.
