What if designers were given
the option to choose only
the parts of phenotypes
that they like?
inverse mapping with sensitivity analysis
sensitivity analysis with
the Morris method
sensitivity analysis with
the Morris method
Premature Convergence
sensitivity analysis with
the Sobol method
Morris heuristic
practical considerations
- Morris requires fewer model evaluations
- Sobol measures quantitative sensitivities more accurately
- Important variables
- model evaluation time
- number of region-of-interest selections
- number of model evaluations
- number of genes
