What’s new in LAGUN (version 26-01-26-I)

FIXED BUGS

  • in Build Surrogate Models tab, BestQ2 remains equal to « BestQ2loo » when Choose Validation is set to Seperate Test File;

  • Lagun study loading has become very slow (it’s due to « logging file with daily rolling », when there are a lot of log files);

  • Lagun study loading sometimes fails, crashing Lagun with error shiny.error.fatal in UQparams$UQparams[[i]];

  • direct optimisation of kind Feasible set learning problem fails if there is only one input;

  • about windows installer:

    • the « nodejs.zip » file is unzipped into the « PROGRAM FILES » directory, not into the directory specified by the user;
    • the environment variables set by Lagun were at the « Machine » level; they are now set at the « User » level.

IMPROVEMENTS

  • Validation criterion based on « Additional Simulations to Refine Surrogate Models »

    Additional points (added from the Build Surrogate Models, Uncertainty Propagation, Sequential Optimisation, Unconstrained/Constrained or Optimisation results sections) are concatenated with any points added via Separate Test File. These points are therefore used for the « Q2Test » calculation and appear in the crossplot.

  • New Launch Simulations button

    A Launch Simulations button is added in the Qualitative Exploration panel, allowing new simulations to be launched from points selected in the Display Data table.

  • New Export DOE as CSV file button

    The simulation launcher’s user interface now has an Export DOE as CSV file button. It allows you to generate files identical to those produced by Lagun’s Export DOE feature.
