Case Studies & Projects
Algorithms behind hard challenges
The most interesting optimization problems rarely exist in isolation. A production sequence changes transport options. A cargo item changes the space remaining for everything else. A sensor assigned to one observation cannot observe another target at the same time.
These accounts look at the work undertaken by 4colors and its collaborators, how the problems were framed, and what the available evidence establishes. A competition result, a proof of concept and an experiment on quantum hardware demonstrate different things. Each deserves its own accurate story.
Quantum and hybrid research
Proof of concept
Testing quantum-enhanced optimization against aerospace planning problems
A proof-of-concept study moves from research ideas toward industrial planning evaluation.
Implemented experiment
Aircraft cargo loading across classical and quantum hardware
A 4colors-led collaboration implemented and evaluated hybrid approaches using different quantum systems.
Competition
Where quantum algorithms might improve classical optimization
The XPRIZE semifinalist work investigates where a quantum component might help inside a broader search.
Networks, scheduling and national research projects
Implemented experiment
Nineteen years, three hundred tasks, a better schedule
How 4colors found new answers to a scheduling challenge that has occupied optimization researchers for nearly two decades.
