In general, the number of possible patterns grows exponentially as a function of m, the number of orders. As the number of orders increases, it may therefore become impractical to enumerate the possible cutting patterns. An alternative approach uses delayed column-generation. This method solves the cutting-stock problem by starting with just a ...
Guillotine cutting is the process of producing small rectangular items of fixed dimensions from a given large rectangular sheet, using only guillotine-cuts. A guillotine-cut (also called an edge-to-edge cut) is a straight bisecting line going from one edge of an existing rectangle to the opposite edge, similarly to a paper guillotine.

[1] Examples include manufacturing parts from flat raw material such as sheet metal, glass sheets, cloth rolls, cutting parts from steel bars, etc. Such process can also be applied to additive manufacturing, such as 3D ...
Additionally, variants where the shapes are circular or even irregular have been studied. In the latter case, it is referred to as irregular strip packing. Dimension: When not mentioned differently, the strip packing problem is a 2-dimensional problem. However, it also has been studied in three or even more dimensions.
The system, PulseSelect Pulsed Field Ablation (PFA), is used for the treatment of atrial fibrillation (AF), a condition that is characterized by an irregular rhythm of the heart. PFA is used for ...
One of the Miami Marlins’ most impactful hitters could be back in the lineup in the not-so-distant future as the team continues to make its push for a spot in the playoffs.
A castellated beam is a beam style where an I-beam is subjected to a longitudinal cut along its web following a specific pattern. The purpose is to divide and reassemble the beam with a deeper web by taking advantage of the cutting pattern. [1]
A beloved brand of vodka is on the rocks (and we don't mean the beverage itself). Last week Stoli Group USA, the American subsidiary of Stoli Group which produces the namesake vodka and other ...
