Reproducibility is fundamental to science. Yet digital technology casts an increasingly long shadow on the principle. When independent investigators examine studies, they are unable to validate about ...

Every year, the countries competing in the International Mathematical Olympiad arrive with a booklet of their best, most ...

Economists argue in guest essay that so-called "price-fixing" software often recommends lowering rents to reduce vacancies.

Abstract: The manufacturing industry encounters numerous optimization problems, one of which is the optimization of storage location assignment (OSLA) problem in logistics. OSLA is a combinatorial ...

Quantum technologies like quantum computers are built from quantum materials. These types of materials exhibit quantum properties when exposed to the right conditions. Curiously, engineers can also ...

Abstract: Intelligent optimization algorithms are currently the mainstream methods for solving engineering design problems. This paper conducts a comprehensive analysis of the performance of five ...

A new computational study suggests the Great Pyramid of Giza was built using a sophisticated "Integrated Edge-Ramp" (IER) system, potentially solving a 4,500-year-old architectural enigma. This model ...
