Job Definition Examples

In this page you will find several examples of job definitions that you can copy and use in your projects. If you would like to add an example to this page or would like us to add a missing example, please contact us.

Basic Jobs

Process a run for 50 generations starting from scratch.

<job filename='MyRun.gep' 
     path='C:\examples' 
     feedback='2'>
    <run id='1' stopcondition='generations' value='50' type='start' />
</job>


Process a run for 100 generations starting from the current model.

<job filename='MyRunWithModels.gep' 
     path='C:\examples' 
     feedback='2'>
    <run id='1' stopcondition='generations' value='50' type='continue' />
</job>


Simplify the active model for 100 generations.

<job filename='MyRunWithModels.gep' 
     path='C:\examples' 
     feedback='2'>
    <run id='1' stopcondition='generations' value='50' type='simplify' />
</job>


Increase the complexity of the active model for 100 generations.

<job filename='MyRunWithModels.gep' 
     path='C:\examples' 
     feedback='2'>
    <run id='1' stopcondition='generations' value='50' type='complexify' />
</job>


Process 4 runs in parallel from scratch and create a run with the best models (selected by Training Fitness) at the end.

<job filename='MyRun.gep' 
     path='C:\examples' 
     feedback='2' 
     usesubfolder='1' 
     createconsolidatedrun='4' 
     async='yes'>
    <run id='1' stopcondition='generations' value='50' type='start' />
    <run id='2' stopcondition='generations' value='50' type='start' />

</job>

For other model selection options see the createconsolidatedrun possible values or the job attributes.

 

Time Series Jobs

Generate a prediction after running for 50 generations and save it to the file prediction.txt

     path='C:\examples' 
     feedback='2'>

</job>

For saving predictions to other formats see here.

Model Selection

Select the model with the best validation fitness and continue the run (improving this model).
