Result database

The result database is a Microsoft Access database containing the fitness values ("QWerte"), the constraint values ("Constraints") and the optimization parameterts ("OptParameter") of each simulation carried out during the optimization process.

By default, the result database is stored in the following location:
C:\Users\[USERNAME]\AppData\Local\Temp\EVO.mdb
If the result database already exists, it is overwritten when starting a new optimization.

Saving

To save the result database to a user-specified location, click on Result - Save result DB after the end of the optimization run or while the optimization is paused.

Loading

You can load an existing result database for the purposes of visualizing and analyzing the results.

  1. Set App, Dataset and Method. These have to correspond to the settings used to produce the result database.
  2. Click on Result - load result DB

It is currently not possible to continue an optimization run using a loaded result database as the starting point.

Structure

Tables

The result database contains several tables:

  • Sim: The simulations that were performed (IDs only)
  • QWerte: Objective function values
  • OptParameter: Optimization parameter values
  • Constraints: Constraint values
  • SekPop: The pareto-front at each generation.

All tables can be linked using the common column Sim_ID.

Queries

Some queries are already predefined:

e.g. OptimierungsErgebnis_PES (nur letzte SekPop) gives you the parameter values, objective function values, and constraint values for all members of the last computed pareto front (i.e. the final result).

Note
The result database does not contain the model parameter values as defined in the MOD-file!
