-# Optimization with Taguchi Grid Search
+### What are taguchi arrays?
 
-To optimize the number of experiments while maintaining comprehensive coverage of parameter combinations, this project uses Taguchi Grid Search. This method, developed by Dr. Taguchi, is a statistical approach that reduces the number of experiments needed by assuming that parameter interactions are negligible. 
+To optimize the number of experiments while maintaining comprehensive coverage of parameter combinations, the grid_search script uses Taguchi Grid Search. This method, developed by Dr. Taguchi, is a statistical approach that reduces the number of experiments needed **by assuming that parameter interactions are negligible**.
 
 The TaguchiGridSearchConverter library (developed by Olivier Cornelis) transforms a full parameter grid into an optimized set of experiments using Taguchi's orthogonal array principles. This allows us to test all parameter combinations with significantly fewer runs while still capturing the main effects of each parameter.
