The Graph Coloring Problem (GCP) is assigning different colors to certain elements in a graph based on certain constraints and using a minimum number of colors. GCP can be drawn into optimization problems. namely the problem of minimizing the color used together with the uncertainty in using the color used. so it can be assumed that there is an uncertainty in the number of colored ver... https://www.nacrack.com/hot-savings-HiBoost-Home-15K-Smart-Link-F20G-5S-IoT-limited-super/
