Comparison and implementation of two methods in a truss optimization, one based in an evolutionary structural optimization, other based in mathematical programming

This paper compares two different methods of a truss optimization. The goal of the optimization is to minimize the compliance of the truss like structures, maximizing the stiffness. The methods used are the Evolutionary Structural Optimization, which is based in slowly removing inefficient material of the structure1, and the Method of Moving Asymptotes, method developed by Kristen Svanberg, based in creating a strictly convex approximated subproblem2, which is solved in each iteration of the optimization process.
