Bin-packing algorithms are essential in combinatorial optimization, helping to allocate objects into bins efficiently. These algorithms, such as First Fit, Best Fit, and advanced metaheuristic methods, are applied in logistics, computing, and manufacturing to enhance space utilization and resource management. Understanding and selecting the right algorithm is key to balancing optimal solutions with computational resources.
