Applications

• In computer science, MOEAs are used to make software better by balancing things like what it can do, how well it runs, and how easy it is to keep working.
• Big companies, like Microsoft, use MOEAs to plan projects better, deciding when they’ll be done, who will do the work, and how much money it will cost.
• In making things, like airplanes, MOEAs help companies, such as Boeing, design them to use less fuel, be safer, and more comfortable for passengers all at once.

Comparative Performance

• Assessing how well different MOEAs work means looking at things like how quickly they find answers, how good those answers are, and how varied they are.
• Experts study MOEAs like NSGA-II, SPEA2, and MOEA/D to see which ones are better at what, and which ones aren’t as good.
• By comparing how these MOEAs perform, people can pick the best one for the job they’re doing, based on how hard the problem is and what kind of answers they need.
