In online three-dimensional packing problems (3D-PPs), unlike offline problems, items arrive
sequentially and require immediate packing decisions without any information about the …

In hierarchical production planning, the consideration of interdependencies between
superior top-level decisions and subordinate base-level decisions is essential. In this …

The sheet metals can be cut into rectangular or irregular pieces, where the main objective is
to minimize the sheet metal's physical waste. However, the operating time, the number of …

About 15 years ago, a paper proposed the first integer linear programming formulation for
the constrained two‐dimensional guillotine cutting problem (with unlimited cutting stages) …

In this paper, we explore the use of reference values (predictors) for the optimal objective
function value of hard combinatorial optimization problems, instead of bounds, obtained by …

Defining the algorithm capable of best fit the characteristics observed for a problem is a
complex task in the context of combinatorial optimization problems. As a decision-making …

We approached the two-dimensional rectangular strip packing problem (2D-SPP), where the
main goal is to pack a given number of rectangles without any overlap to minimize the height …

The present paper describes a methodological framework developed to select a multi-label
dataset transformation method in the context of supervised machine learning techniques …

Defining the algorithm capable of best fit the characteristics observed for a problem is a
complex task in the context of combinatorial optimization problems. As a decision-making …

In the two-dimensional strip packing problem, the objective is to pack a set of rectangular
items in a non-overlapping manner into a single, rectangular object of xed width but …
