Bin packing algorithms packing with as few bins/boxes as possible BoxABCDEFGHIJ HEIGHT (M) 0.80.60.70.50.90.40.30.60.50.6

10
Full bin combinations only suitable for small problems BoxABCDEFGHIJ HEIGHT (M) 0.80.60.70.50.90.40.30.60.50.6 Example A + C 8+7=15 FULL BIN B + E6+9=15 FULL BIN H + J + G6+6+3=15 FULL BIN D + I + F 5+5+ 4=14REMAINING BIN
