Method: ColumnPack::BinPacker#initialize

Defined in:
lib/column_pack/bin_packer.rb

#initialize(total_bins, options = {}) ⇒ BinPacker

Uses a fixed number of bins (total_bins).

Options: :algorithm specify a different bin packing algorithm (default :best_fit_decreasing)

available algorithms are :best_fit_decreasing, :best_fit_increasing

:shuffle_in_col after packing columns, shuffle the elements in each column (defaults to true)

Raises:

  • (ArgumentError)
