This paper puts forward a constructive heuristic algorithm called the method of inserting the minimum neighbor edge from outside to the center (IMNEFOTC) that can be applied to solve large-scale and ultra-large-scale travelling salesman problems. Through it and the randomized greedy heuristic algorithm (RGH) which greedy heuristic algorithm is modified. a general meta-heuristic search... https://www.roneverhart.com/Oakley-SI-Holbrook-Multicam-Men-s-Lifestyle-Polarized-Sunglasses-Brand-New/
