App based in 1D bin packing algorithm.
In machine shops, you purchase metal rods in standard sizes and later you cut them in small pieces on Power Hacksaw.
This App helps you in reducing wastage in this activity. Suppose, you have two bars 100 Cm long and you want 8 pieces of 15 Cm and 4 pieces of 20 Cm.
One combination is 15x6 = 90 in first Rod : 10 cm wastage.
15x2 = 30 and 20x3=60 in second rod : 10 cm wastage
20x1 = 20 in third rod.
You require three rods here.
Instead, this app sugguests:
15x4 = 60 and 20x2 in first rod : No wastage
15x4 = 60 and 20x2 in second rod: No wastage
You require two rods here and there is no wastage
