“…Algebraic approaches In the literature several algebraic approaches and their proof are available for constructing Golomb ruler sequences. The best known construction algebraic approaches to produce Golomb rulers are Extended quadratic congruence (EQC) and Search algorithm (SA), Erdös-Turan, Rusza-Lindström, Bose-Chowla, Singer, and Symmetric Golomb Costas arrays constructions [1,15,41,46]. The construction approaches EQC and SA proposed in [1,15] works always, but, unfortunately, are far from optimal and are limited to prime number of marks.…”

“…To suppress the crosstalk due to FWM signals in optical WDM systems, several unequally spaced channel allocation (USCA) algorithms have been proposed in the literatures [1,[10][11][12][13][14][15][16]. However, the algorithms [1,[10][11][12][13][14][15][16] have the drawback of increased optical bandwidth requirement compared to the equally spaced channel allocation (ESCA).…”

Nowadays, nature-inspired metaheuristic algorithms are most powerful optimizing algorithms for solving the NP-complete problems. This paper proposes three approaches to nd near-optimal Golomb ruler sequences based on nature-inspired algorithms in a reasonable time. The optimal Golomb ruler (OGR) sequences found their application in channel-allocation method that allows suppression of the crosstalk due to four-wave mixing in optical wavelength division multiplexing systems. The simulation results conclude that the proposed nature-inspired metaheuristic optimization algorithms are superior to the existing conventional and nature-inspired algorithms to nd near-OGRs in terms of ruler length, total optical channel bandwidth, computation time, and computational complexity. Based on the simulation results, the performance of proposed di erent nature-inspired metaheuristic algorithms are being compared by using statistical tests. The statistical test results conclude the superiority of the proposed nature-inspired optimization algorithms.
