Optimization Benchmark Truss Problems

MATLAB codes for modeling and analysis of the benchmark optimization problems

MATLAB codes for modeling and analysis of three benchmark structural optimization problems are provided in this submission. These benchmark truss problems (10-bar truss, 25-bar truss, and 72-bar truss) have been used in many structural optimization studies in the literature for many years.
