You know how sometimes you need to find the best of two things at once, like the strongest but lightest bridge? Well, researchers have come up with a cool algorithm that does just that. It's called the 2-Archive Multi-Objective Cuckoo Search (MOCS2arc) and it helps find the best balance between two things, like the weight and strength of a bridge.

Scientists tested this new method on some classic truss structures, which are like the skeletons of bridges, and on some special math problems called ZDT functions. The goal was to make these structures as light as possible while keeping them strong.

MOCS2arc is like an upgrade of an older method called Multi-Objective Cuckoo Search (MOCS). It uses a clever trick called a "dual archive strategy" to make sure it finds diverse and really good solutions.

To see how well MOCS2arc worked, the scientists compared it to a bunch of other methods like MOSCA, MODA, MOWHO, MOMFO, MOMPA, NSGA-II, DEMO, and the original MOCS. They used different measures to see which method was best at finding good and varied solutions.

Guess what? MOCS2arc came out on top! The results showed that it found better solutions and a wider variety of them too. Special tests called Friedman's and Wilcoxon's tests also showed that MOCS2arc was consistently better than the others.

So, if you're looking for a way to make things both strong and light, MOCS2arc might be your answer. It's a really promising improvement over other methods.
