Perhaps you should try some spelling variations:
simulation techniques » mitigation techniques, segmentation techniques, inhalation technique
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
n simulation » _ simulation, a simulation, _ simulations
based code » based anode
based n » based _, based k, based no2

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( learning-based n simulation techniques ) or ( learning-based code imputation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based n simulation techniques ) OR ( learning-based code imputation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based n simulation techniques ) or ( learning-based code imputation techniques ))*.
