Internal combustion engines have played a vital role in shaping modern society, powering everything from automobiles to power plants. However, these engines have traditionally been designed using a trial-and-error approach, resulting in suboptimal designs that often fail to meet today's stringent environmental and performance standards.

Computational optimization, a powerful tool that combines computational power with optimization algorithms, is revolutionizing the design of internal combustion engines. By simulating engine behavior and optimizing design parameters, engineers can explore a vast design space and identify optimal solutions that would be difficult or impossible to find using traditional methods.
