Corrections to "Lightpath (Wavelength) Routing in Large WDM Networks" and "Dynamic Routing and Assignment of Wavelength Algorithms in Multifiber Wavelength Division Multiplexing Networks"

In this comment, several errors in Chlamtac et al., 1996, Lightpath (Wavelength) Routing in Large WDM Networks and one error in Xu et al., 2000, Dynamic Routing and Assignment of Wavelength Algorithms in Multifiber Wavelength Division Multiplexing Networks are pointed out. We present corrections to the errors.
