“…Scheduling DATs to improve NL is a known NP complete problem, 7 and several researchers have devised DAT construction techniques which suboptimally distribute the energy consumption of the nodes. [6][7][8][9][10][11][12][13][14][15]17,18 These techniques include various algorithmic strategies like approximation, [7][8][9][19][20][21] heuristics, 6,10,[15][16][17][18][22][23][24][25] soft computing, 26 linear programming, 27 genetic algorithms, and evolutionary algorithms. [28][29][30] Recent nature inspired meta-heuristic optimization algorithms such as black window optimization, 31 whale optimization, 32 and gray wolf optimization approaches 33 facilitate to solve NP complete problems.…”
