%description
Basic infrastructure and several algorithms for 1d-4d bin packing problem.
This package provides a set of c-level classes and solvers for 1d-4d bin
packing problem, and an r-level solver for 4d bin packing problem, which
is a wrapper over the c-level 4d bin packing problem solver. The 4d bin
packing problem solver aims to solve bin packing problem, a.k.a container
loading problem, with an additional constraint on weight. Given a set of
rectangular-shaped items, and a set of rectangular-shaped bins with weight
limit, the solver looks for an orthogonal packing solution such that
minimizes the number of bins and maximize volume utilization. Each
rectangular-shaped item i = 1, .. , n is characterized by length l_i,
depth d_i, height h_i, and weight w_i, and each rectangular-shaped bin j =
1, .. , m is specified similarly by length l_j, depth d_j, height h_j, and
weight limit w_j. The item can be rotated into any orthogonal direction,
and no further restrictions implied.
