JSS30 Two bar truss and geometry design problems with DESDEO framework

You can find all necessary python files from the root folder. Information on precalculated solutions can be found from HERE.

Python files

Creating the problems

One can use these files to create DESDEOs MOProblem instances of two bar truss problem or either one of the geometry design problem. You can find examples on creating the problem from the file itself. The 'Non successful optimization' log can be ignored.

file name	Details
createTwoBartrussProblem.py	Creating a two bar truss problem
createGeometryDesignProblem.py	Creating the default geometry design problem
createFloorGeometryDesingProblem.py	Creating the 2 dimensional (surface area and volume) geometry design problem with constant floor

Visualizing the solutions

For the geometry design problems (< 4d) one can use interactive scatter plots which will scatter the objectives values and by clicking any point from the scatter plot a tent representation will be plotted of the corresponding decision variables.

Examples of both scatter plots and parallel plots can be found from the files

file name	Details
visualizeTwoBarTruss.py	Visualizing the two bar truss problem
visualizeGeometryProblem.py	Visualizing the default geometry design problem
visualizeFloorGeometryProblem.py	Visualizing the geometry design problem with constant floor with interactive scatter plot

Making tents

The tentExample.py file has a few examples on constructing Tents and how to use them. Also a few mentions on some caveats.
