WebIn the "First fit" heuristic, items are again considered in the given order and an item is placed in the smallest numbered bin in which it fits. In the same example, Item 1: 3 is placed in bin 1: {3}. Item 2: 4 does not fit in bin 1. A new bin is started for it: {3}{4}. Item 3: 2 is placed in bin 1, the first bin in which it fits: {3,2}{4}.
