Basic infrastructure and several algorithms for 1d4d bin packing problem. This package provides a set of clevel classes and solvers for 1d4d bin packing problem, and an rlevel solver for 4d bin packing problem, which is a wrapper over the clevel 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 rectangularshaped items, and a set of rectangularshaped bins with weight limit, the solver looks for an orthogonal packing solution such that minimizes the number of bins and maximize volume utilization. Each rectangularshaped item i = 1, .. , n is characterized by length l_i, depth d_i, height h_i, and weight w_i, and each rectangularshaped 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.
