Basic Usage

In this section, we will briefly illustrate how to use AutoOED through a very simple test case. More detailed explanations of AutoOED can be found in the User Manual of this documentation.

Step 1: Starting Software

If you directly installed the executable file of the software, then simply double-click the executable file to start. Otherwise, if you installed the software through source code, please run


The software will start with this window:


Next, click Create Task.


You need to input a name for your new task, which cannot be the same as existing tasks. Then, click Create to create the task, and AutoOED will enter the main interface:


Step 2: Building Problem

Now we are going to build a problem for optimization. Click Problem->Manage from the menu, then this window will show:


The list of the current problems that have been created is shown on the left, which is empty now. We can start by clicking Create. Just as an example, we create the continuous ZDT1 1 optimization problem, named “myzdt1”.


Next, we specify the information of the design variables. In this problem, we have 6 design variables bounded by 0 and 1.


After that, we specify the information of the performance space. In this problem, we have 2 objectives that are supposed to be minimized.


And we have linked a performance evaluation program (objective function) for this problem, which is a simple python script like this, defined by the original ZDT1 problem:

import numpy as np

def evaluate_objective(x):
    n_var = 6
    f1 = x[0]
    g = 1 + 9.0 / (n_var - 1) * np.sum(x[1:])
    f2 = g * (1 - np.power((f1 / g), 0.5))
    return f1, f2

As the last step, we specify the information of the constraints. But in this case, the problem does not have any constraints, so it appears like:


Finally, we click Finish and the problem list gets updated:


Step 3: Building Experiment

Now let us get back to the main interface. After building the problem, now we are building an experiment to optimize that problem.


Click Config->Create from the menu, then this window will show:


First, we select our “myzdt1” problem that we just created from the problem list. Next, we choose “DGEMO” as the optimization algorithm, using only 1 process (and of course, more processes means faster optimization). Then, we want to have a random initialization with 10 samples generated by AutoOED.


Finally, we can click Save to build the experiment without worrying about other optional parameters.

Step 4: Running Optimization

Then we can see the initialization is taking place and the software interface becomes:


We can see our 10 initial samples from the performance space figure, where they are colored as blue and the Pareto-optimal ones are colored as red. When you double click some points in the performance space, the values of the corresponding design variables will appear on the radar plot shown on the right.

Next, we set the batch size as 5 and click the Optimize button for optimizing our first batch of samples, the optimzation results will be like:


As you can see, AutoOED proposes 5 new samples that significantly outperform the initial samples, which are shown in magenta and become the new Pareto front. And since we have the performance evaluation program linked when we created the problem, AutoOED automatically evaluates them such that their performance appear in the performance space figure.

Besides the visualization for performance space and the selected design sample, here is the statistics of our optimization history:


And here is the display for the database which stores all the historical data.


Currently we have only optimized the problem for only 1 iteration, but you can continue on that until you are satisfied with the results.

Concluding Remarks

So that is it! We have shown you how to start the software, build the problem and the experiment for optimization, and run the real optimization using AutoOED. This is just a very brief introduction of a simple use case. For more details, we suggest you go through the user manual and explore more advanced features of AutoOED. Hope our software can boost your experiments!
