A Tool for Designing Bar Structures
Every structure designed with Ebe is described in a .ebe file. These files are used as input data to configure a jMetal problem that can be solved with many of the provided multiobjective metaheuristics.
In this page, we include some structures, providing for each of them:
Problem name  Description  Figure  .ebe file  Pareto front approximation 

Bridge25N35B8G  Mobile cablestrayed bridge with 25 nodes, 35 bars, 8 groups  File 
Algorithm: NSGAII 

Bridge33N221B33G  Cablestrayed bridge with 133 nodes, 221 bars, 33 groups  File 
Algorithm: NSGAII 
The optimization of the structural design problems with jMetal requires to follow these steps:
The encoding of the solutions of the Ebes problems is real, so most of the multiobjective metaheuristics provided by jMetal can be applied.
Depending on the complexity of the problem, the total running time of an optimization can be very high. Some examples:
Computer: MacBook Pro, 2.2GHz Intel Core i7, 8 GB 1333 MHz DDR3, MacOS X 10.9.2, Java(TM) SE Runtime Environment (build 1.8.0eab94)
The current implementation of Ebes problems in jMetal is not threadsafe, so multithreaded algorithms such as pMOEAD, pNSGAII, and pSMPSO cannot be used.
