The trusses are the most used structural systems employed by engineers in designing bridges, arches, domes, etc. However, limitation in resources and high construction costs in such engineering structures require optimal designs, and finding an optimum solution is challenging. These well-known benchmark design cases are solved using the MFO algorithm to show that the proposed MFO is more efficient than other earlier metaheuristics for continuous optimization. Consider the following scenarios to show the effectiveness of the MFO algorithm: a 25-bar space truss, a 72-bar space truss, and a 200-bar planar truss. Each problem results are compared to solutions developed using a variety of other optimization approaches. The suggested technique has 200 iterations for 25- and 72-bar space trusses and a total of 400 iterations for a 200-bar planar truss, and each example uses a population of 50 particles.
