binPack: Simple bin packing.

In berndbischl/BBmisc: Miscellaneous Helper Functions for B. Bischl

Simple bin packing.

Description

Maps numeric items in x into groups with sum less or equal than capacity. A very simple greedy algorithm is used, which is not really optimized for speed. This is a convenience function for smaller vectors, not a competetive solver for the real binbacking problem. If an element of x exceeds capacity, an error is thrown.

Usage

binPack(x, capacity)

Arguments

x	[numeric] Numeric vector of elements to group.
capacity	[numeric(1)] Maximum capacity of each bin, i.e., elements will be grouped so their sum does not exceed this limit.

Value

[integer]. Integer with values “1” to “n.bins” indicating bin membership.

Examples

x = 1:10
bp = binPack(x, 11)
xs = split(x, bp)
print(xs)
print(sapply(xs, sum))
