Struct BPInstance

pub struct BPInstance {
    pub items: Vec<(Item, usize)>,
    pub item_area: fsize,
    pub bins: Vec<(Bin, usize)>,
}

Bin-packing problem instance: a set of items to be packed into a set of bins. The items are to be packed in such a way that the total cost of the bins used is minimized.

Fields

items: Vec<(Item, usize)>

Items to be packed in the instance, along with their requested quantities

item_area: fsize

Total area of all items in the instance

bins: Vec<(Bin, usize)>

Set of bins available to pack the items, along with their quantities
