Ebes+jMetal is a software package that allows to design bar structures which can further be optimized with multi-objective metaheuristics according to different goals, such as minimizing the structure weight and minimizing the deformation.
Ebes is a software application aimed at the design, calculus, and analysis of 2D and 3D bar structures.
jMetal stands for Metaheuristic Algorithms in Java, and it is an object-oriented Java-based framework for multi-objective optimization with metaheuristics. The object-oriented architecture of the framework and the included features allow you to: experiment with the provided classic and state-of-the-art techniques, develop your own algorithms, solve your optimization problems, integrate jMetal in other tools, etc.
