Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
reduction techniques » reduction technique, imputation techniques
cross reduction » closed reduction, cross section
co simulation » _ simulation, a simulation, 3d simulation
based cross » based roms, based access, based closed
based co » based code, based no2, based two

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 cross reduction techniques ) or ( learning-based co simulation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based cross reduction techniques ) OR ( learning-based co simulation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based cross reduction techniques ) or ( learning-based co simulation techniques ))*.
